Figure 9: SEL-351P-3 Voltage Connector Options

Making the PT Ratio Setting for the Various SEL-351P-3 Options in

Figure 9

Figure 9(a) shows the traditional (300 Vac) voltage inputs, where the PT

Ratio setting (see the Settings section) is set with the ratio of the external primary potential transformers (not shown).

Figure 9(b) and Figure 9(c) have low-level (3 Vac) voltage inputs. The

SEL-351P-3 does not internally scale these low-level (3 Vac) voltage inputs any different than the traditional (300 Vac) voltage inputs. Thus,

1.2 Vac applied to the low-level (3 Vac) voltage inputs appears the same to the SEL-351P-3 as 120 Vac applied to the traditional (300 Vac) voltage inputs. Thus a PT Ratio setting made for the low-level (3 Vac) voltage inputs has to take into account this factor of 100 (= 300 Vac/

3 Vac) difference. For example, if the external voltage step-down device

(for the low-level [3 Vac] voltage inputs) has a ratio of 10,000, then it would need to be adjusted by this factor of 100 for a PT Ratio setting:


Installation

PT Ratio = 10,000 x (1/100) = 100

This adjusted PT Ratio setting makes the primary voltage metering correct. The secondary voltage metering values for the low-level (3 Vac) voltage inputs still appear as 100 times their actual magnitude (e.g., 1.2

Vac applied to the low-level [3 Vac] voltage inputs appears as 120 V secondary in the secondary voltage metering)—nothing can be done about this.

Voltage elements in the “regular” settings (see the SEL-351P-3

Instruction Manual ) are set in Volts secondary. Thus, for a voltage element to pick up for 1.2 Vac applied to the low-level (3 Vac) voltage inputs, the voltage element pickup in the SEL-351P-3 needs to be set at

120 V secondary (= 1.2 x 100). Again, the factor of 100 (= 300 Vac/

3 Vac) comes into play for the low-level (3 Vac) voltage inputs.

If the PT Ratio setting does not apply to all the voltage inputs (voltage inputs V1, V2, and V3 require a different setting than voltage input VS, as is likely in Figure 9(b) with its mixture of 3 Vac and 300 Vac voltage inputs), then separate potential transformer ratio settings are needed (see

“regular” settings PTR and PTRS discussed in the SEL-351P-3

Instruction Manual ).

Figure 11: SEL-351P-3 Current Connector J11

The interposing current transformers in Figure 11 are integral to particular GVR Recloser models. They require the particular SEL-351P-3 current inputs shown in Figure 11 and further explained/referenced in

Table 1. The winding turns of the interposing current transformers are literally the turns on the indicated sides. For current passing through the interposing current transformers (left-to-right), the current is transformed down:

• by a factor of 1/200 (= 5/1000) for current inputs I1, I2, and I3

• and by a factor of 1/20 (= 50/1000) for current input IN

For example, 1 A from the primary current transformers on the left-hand side of Figure 11 is transformed down to

• 0.005 A [= 1 A x (1/200)] for current inputs I1, I2, and I3

• and 0.05 A (= 1 A x (1/20)] for current input IN after it passes (left-to-right) through the interposing current transformers.


Installation

Making the CT Ratio Setting for the SEL-351P-3 in Figure 11

The CT Ratio setting (see the Settings section) is traditionally set with the ratio of the primary current transformer (the current transformers on the left-hand side of Figure 11, transforming primary current to secondary levels). For example, if the primary current transformers on the left-hand side of Figure 11 are ratio 400, then the traditional setting is: CT Ratio =

400.0.

But, Figure 11 is a unique setup, with the combination of the interposing current transformers inside the GVR Recloser and the internal

SEL-351P-3 low-level current-input circuitry on the right-hand side. With this unique setup, a traditional CT Ratio setting causes primary current to appear as half the true magnitude to the SEL-351P-3. Thus, if 400 A primary is flowing on the primary system on the left-hand side of

Figure 11, the SEL-351P-3 on the right-hand side (with setting CT Ratio

= 400.0) only perceives 200 A primary. Likewise, the SEL-351P-3 perceives only half the true secondary current. For example, if there is 1 A secondary flowing out of the primary current transformers on the left-hand side of Figure 11, the SEL-351P-3 on the right-hand side perceives only

0.5 A secondary. This “half magnitude” perception on the part of the

SEL-351P-3 in Figure 11 applies to all the current channels I1, I2, I3, and

IN.

The solution to this “half magnitude” problem for the SEL-351P-3 in

Figure 11 (for primary current values) is to double the CT Ratio setting.

Thus, a traditional setting of CT Ratio = 400.0 (for primary current transformers of ratio 400) is doubled to CT Ratio = 800.0 (= 2 x 400.0).

Then, primary current metering values appear correct and EZ settings made in Amps primary (see the Settings section) are made as they normally would be, without any adjustment.

This “doubling of the CT Ratio setting” to handle primary current values

(metering and EZ settings) makes no change to secondary metering values from the SEL-351P-3 in Figure 11—secondary metering values still appear as half the traditionally expected magnitude—nothing can be done about this. Likewise, if “regular” settings are made in Amps secondary

(not in Amps primary, as with the EZ settings in the Settings section), then adjustments would have to be made. For example, if a “regular” setting is traditionally set 1 A secondary, then it would be set 0.5 A secondary instead, for a Figure 11 setup. “Regular” settings (made in

Amps secondary) are discussed in the SEL-351P-3 Instruction Manual .

For many traditional recloser installations, only EZ settings need be made

(see the Settings section) and “regular” settings do not have to be made.

Installation

Mounting

Room for Connectors and Wiring:

The dimensions in Figure 1 do not make any allowances for connectors and wiring that may be attached to the side panel

(see Figure 12). Some connections (e.g., fiber-optic modems) can protrude up to 4 inches (about 10 cm) out from the surface of the side panel.

Refer to Figure 1 and Figure 2.

Panel Cutout

The front view dimensions 7.00 x 13.00 inches (177.8 x 330.2 mm) refer to the panel cutout dimensions needed for mounting the SEL-SEL-351P-3.

The panel cutout dimensions are slightly smaller than the SEL-351P-3 front-panel overlay, thus providing appropriate coverage of the

SEL-351P-3 front panel when mounted, yet allowing for front panel interface access. SEL-351P-3 front panel overlay details can be seen in

Figure 16 (English) and Figure 17 (Spanish).

Mounting Holes

The six mounting holes are each 0.20 inch (5.2 mm) diameter. A size #6-

32 bolt or mounting stud, with lock nuts is recommended.

The two studs on both the top and bottom of the SEL-351P-3 can be used to attach wire clamps for a wire harness draped over the top of the unit (or underneath). The studs accept #10-32 lock nuts.

Side Panel Connections

Refer to Figure 3 through Figure 12. Figure 9 through Figure 12 show what is “behind” the side panel connections shown in Figure 3 through

Figure 8. See Table 1 for all voltage and current options/ratings.

!

WARNING: Connect the GROUND terminal to ground before making any other connection on the side panel. The GROUND spade is 0.25 x 0.03 inches (6.4 x 0.8 mm).

Explained in Other Sections:

The serial ports and IRIG-B shown in Figure 12 are explained in the Communications section. The front-panel

LEDs and operator controls are explained in the Front-Panel

Interface section.

Extra I/O

The extra I/O (output contacts OUT101 through ALARM and optoisolated inputs IN101 through IN106) is not needed for the basic recloser control functions. The extra I/O is available for SCADA connection or other control and is not polarity sensitive. See the

Specifications section for ratings.

The connectors for the extra I/O accept wire size AWG 24 to 12. Strip the wires to 0.3 inch (8 mm) and install with a small slotted-tip screwdriver.


Installation

User-Supplied Connectors

Connectors J3 through J11 (depending on model; see Table 1 and its figure references) on the side panel are the receptacle end (female), with recessed male terminals inside. The user supplies the complementary plug end (male), with recessed female terminals inside. Each plug end (male) is a different size and uniquely keyed and cannot be inserted into any other receptacle end (female):

The user-supplied plug ends (male) require the following corresponding female terminals be installed in a recessed fashion inside the connector:

Molex order no. 39-00-0055

Tyco

Souriau order no. 770008-4 order no. SM20M1S6

Special tools and procedures are required to install terminals/wiring into the user-supplied connectors.

Current and Voltage Connections

See Table 1 for all voltage and current options/ratings.

The SEL-351P-3 has three analog voltage input terminal connections labeled V1, V2, and V3. Wiring to the power system (potential transformer connections and recloser primary bushing connections) can be random, but correct power system “A-B-C” designation is still needed within the SEL-351P-3 algorithms. EZ Settings and Global EZ settings

(True three-phase voltage connected, Phantom voltages, V123 Terminal

Conn., I123 Terminal Conn., CT Polarity) define how transition occurs between the power system wiring and the SEL-351P-3 relay algorithm.

Frequency Measurement

Voltage input V1 (VOLTAGES connector) also provides the frequency measurement (e.g., for underfrequency load shedding).

Voltage Inputs

Voltage inputs V1, V2, and V3 are the three phase voltage inputs. Voltage input VS is the synchronism check voltage input. Voltage input VS can be used for other functions besides just synchronism check—see Section 3 in the SEL-351P-3 Instruction Manual .


Enable Fault Location if

Three-Phase Voltage is connected:

Use SET n command

[n = 1 (main settings), n = 2 (alternate settings)]

Make the line parameter settings:

Z1MAG, Z1ANG

Z0MAG, Z0ANG, LL

Enable fault locating:

EFLOC = Y

See SET commands in Table 3 in the Communications section.

Installation

Current Inputs

Residual current is derived internally from phase current channels I1, I2, and I3. Residual ground overcurrent elements operate off of this derived residual current.

Neutral ground and sensitive earth fault (SEF) overcurrent elements operate off of current channel IN.

The EZ settings presume that current channel IN is connected residually with phase current channels I1, I2, and I3 by the user. This is required to satisfy the pickup range sensitivity for fast and delay curve-ground overcurrent elements (i.e., for the current input option in Figure 10; for ground overcurrent element pickups below 0.1 A secondary, a neutral ground overcurrent element is used automatically; for ground overcurrent element pickups 0.1 A secondary and above, a residual ground overcurrent element is used automatically).

See the Settings section for more EZ settings details.

POWER Connector J6 and POWER IN Connector J7 Details

Power Supply Connection:

Only one 120/240 Vac power supply connection is made, either to connector J7

(terminals 1 and 2) or to connector J6 (terminals 4 and

8). See Figure 12 and accompanying side-panel note.

24 Vdc Battery

The 24 Vdc battery to power the SEL-351P-3 and external trip/close capacitors (when Vac power is not present on terminals 1 and 2 of

POWER IN connector J7) is connected to POWER connector J6, terminals 6 (+) and 2 (–). See the Battery section for more details.

NOTE: Anytime nominal Vac power is applied to the SEL-351P-3

(terminals 1 and 2 of POWER IN connector J7), the unit automatically turns on and the AC SUPPLY/ALIM CA LED illuminates.

If no power is connected to the SEL-351P-3 (unit is off) and then 24 Vdc battery power is connected to POWER connector

J6 terminals 6 (+) and 2 (–), the unit remains off until the

WAKE UP/DESPERTAR operator control is pressed.

12 Vdc Power Output

12 Vdc power is available on POWER connector J6, terminals 5 (+) and 1

(–). It is used for such applications as powering radios. It is currentlimited and has the following specifications:

Voltage Range Fluctuation: 11–14 Vdc

Maximum Capability: 6 W continuous; 13 W for one second

!

WARNING: No grounds can be installed on the circuits connected to the 12 Vdc voltage source. This voltage source is grounded inside the SEL-351P-3.


Installation

CONTROL Connector J5 Details

Figure 13 shows greater detail on what is connected to either side of

CONTROL connector J5.

Fuse the 24 Vdc

Whetting Voltage:

Read Note1 in Figure 13.

24 Vdc Whetting Voltage

The 24 Vdc voltage on terminal 1 whets the 52a and 52b breaker auxiliary contacts, which are connected through terminals 5 and 13, respectively. It can also whet the 24 Vdc optoisolated inputs IN101 through IN106 using terminal 9 as a return.

Optoisolated inputs IN101 through IN106 can be configured via settings to operate on ac voltage. See the Optoisolated Input Ratings subsection in the Specifications section for more information on ac operation.

!

WARNING: No grounds can be installed on the circuits connected to the 24 Vdc whetting voltage.

This voltage source is grounded inside the SEL-351P-3.

Connect Battery and Charge

Capacitors for Auto-

Reclosing

Factory-default settings require that the 24 Vdc battery be connected and healthy and the trip and close capacitors be fully charged in order for autoreclosing to proceed after a reclose interval times out.

Capacitor Voltage Monitor and Charger Control

Terminals 6 and 14 monitor trip and close capacitor voltages, respectively.

Terminal 6 indicates when the trip capacitor is fully charged (> 80 V).

The presumption is if the trip capacitor is fully charged to > 80 V, the close capacitor is, likewise, fully charged.

Terminal 14 indicates when the close capacitor is charged to at least 20 V.

Exceeding this 20 V threshold causes the capacitor charger control output

(terminals 10 and 2) to go below 24 Vdc (it is nominally 40 Vdc). This low output signal to the external capacitor charger causes the charger to go to a higher charge rate to quickly charge the capacitors to 90 V.

External Power Supply

An external power supply is also supplying power to the external trip/close capacitor charger, if ac power is present.

If ac power is off, then the external power supply provides no power and the 24 Vdc battery is the only source of power (via the closed Boost

Power Switch) for the external trip/close capacitor charger.

Boost Power Switch

The Boost Power Switch on terminal 16 is usually open when ac power is present. This allows the battery charger inside the SEL-351P-3 module to charge the 24 Vdc battery without outside interference.

The Boost Power Switch closes for any of the following occurrences:

• Trip

• Close

• Start of reclose cycle

• Loss of ac power

The closed Boost Power Switch provides 24 Vdc battery power to an external trip/close capacitor charger. Thus, the battery charger is turned


Installation off while the Boost Power Switch is closed. About two minutes after trip, close, and reclose cycle operations cease (and if ac power is present), the

Boost Power Switch opens again and battery charging resumes.

If the Boost Power Switch is closed due to loss of ac power, it remains closed until the 24 Vdc battery is automatically disconnected (discharging for too long or battery voltage too low—see battery-related settings in the

Battery section). If ac power returns sooner, then there is about a two minute delay before the Boost Power Switch opens again and battery charging resumes.

Trip and Close Outputs

Combinations of FET outputs connected to terminals 7, 8, and 15 provide tripping/closing of the recloser by energizing the magnetic actuator in one direction or the other. The FET outputs are connected in an H-bridge arrangement, with the magnetic actuator in the middle of the H-bridge circuit. The magnetic actuator causes the recloser to:

• open for current in the “trip” direction

• or close for current in the opposite/”close” direction

When the SEL-351P-3 trips the recloser, one trip FET output turns on to connect the trip capacitor (terminal 6) to the magnetic actuator (terminal

7). The other trip FET output completes the circuit from terminal 15 to the capacitor return on terminal 8. At the end of the trip operation, the trip

FET outputs turn off, forcing the extinguishing of the trip current.

When the SEL-351P-3 closes the recloser, one close FET output turns on to connect the close capacitor (terminal 14) to the magnetic actuator

(terminal 15). The other trip FET output completes the circuit from terminal 7 to the capacitor return on terminal 8. At the end of the close operation, the close FET outputs turn off, forcing the extinguishing of the close current.

SF6 Pressure Sensor

Terminals 3 and 11 provide whetting voltage for the SF6 gas pressure sensor on the recloser. Terminals 4 and 12 take in the SF6 gas pressure sensor signal and compare it to an EZ setting threshold for low pressure indication. See the Settings section for more EZ settings details.


Installation

Checks Before the SEL-351P-3 Is Put in Service

! CAUTION: Do not connect the SEL-351P-3 to an energized recloser until all control settings have been properly programmed and verified and all front-panel operator controls are in their proper state (see

Figure 16 or Figure 17). Refer to the Settings section of this guide for programming procedures. Failure to comply can result in control and recloser misoperation, equipment damage, and personal injury.

Settings Group 3

With factory settings, the LIVE

LINE ENABLED/LINEA VIVA

HABILITADA operator control activates Settings Group 3 when it is engaged—see explanation in the Operator

Controls subsection in the

Front-Panel Interface section.

Thus, certain future settings changes made to Settings

Groups 1 and/or 2 should perhaps be made to Settings

Group 3, too.

If the alternate settings are not going to be used, copy the main settings

(Settings Group 1) to the alternate settings (Settings Group 2) with the

COPY command (i.e., COP 1 2 ; see Table 3 in the Communications section). The settings in both settings groups will then be the same. If the

ALTERNATE SETTINGS/AJUSTES ALTERNATIVOS operator control pushbutton is accidentally pressed (switching the active settings group), the SEL-351P-3 still operates on the same settings. Refer to the

Factory EZ Settings subsection in the Settings section for more information on main and alternate settings.

Set the date and time with the DATE and TIME commands ( DAT and

TIM , respectively; see Table 3 in the Communications section).

OMMUNICATIONS

Topics covered in this section:

• Serial Port Connectors

• Communications Cables

• Commands

• Access Levels

• Password Protection

You can view and change control settings, and obtain event and status information either from the front-panel interface or via one of the serial ports.

You can access many of the features of the SEL-351P-3 from the front panel; however, some features can only be accessed from one of the serial ports. Table 3 provides the serial port commands (with descriptions) as well as the corresponding front-panel pushbutton, if applicable.

Getting Started With Communications

Before you attempt communications with the SEL-351P-3, via either the serial ports or the front-panel interface, the following precautions must be taken:

Hint:

For the best display, use

VT-100 terminal emulation or the closest variation.

• Verify that the SEL-351P-3 has been properly installed and that the settings have been programmed by qualified personnel.

Terminal Emulation

Programs:

Examples of PC-based terminal emulation programs include: ProComm Plus ® ,

Relay Gold ® , Microsoft ®

Windows ® Terminal and

HyperTerminal, SmartCOM ® , and CROSSTALK ® .

• Become familiar with and understand the information presented in the Communications, Front-Panel Interface , and Settings sections.

For serial port communications, the previous two precautions apply. You must also carry out the following:

• Select the appropriate communications cable (usually SEL Cable

C234A—see Table 2).

Default Settings for Front

Panel Serial Port:

Baud Rate = 38400

Data Bits = 8

Parity = N

Stop Bits = 1

• Choose a terminal emulation program on your personal computer

(PC) to communicate with the SEL-351P-3.

• Set the communications parameters for the connected PC communications port to the default settings. (Press the ENTER key, and the SEL-351P-3 will respond with a “=” prompt, which indicates Level 0 access is established—see Table 5.)


Communications

Communications Connections Example

You can connect the serial port to a computer serial port for local communications or to a modem for remote communications. Other devices useful for automated communications are SEL Communications

Processors.

You can use a variety of terminal emulation programs on your personal computer to communicate with the SEL-351P-3. Figure 14 presents some example SEL-351P-3 communications connections (see Table 2 and contact SEL for more information).

To obtain event report information use the EVE command. There are numerous options that allow you to customize event information. For descriptions and examples of all options, refer to the SEL-351P-3

Instruction Manual . The general command format is:

EVE [ n A D ]


Communications

The parameters in brackets [ ] are optional. The following table defines the parameters [ n A D ] that can be issued with the EVE command to customize the report format.

Table 4: Event Report Parameters

Parameter n Choose event number (1–28). Defaults to 1 if not specified.

Description

A Specifies that the analog section of the event is to be displayed (current, voltage, frequency, contact outputs, and optoisolated inputs).

D Specifies that the digital section (Protection and Control

Elements) of the event is to be displayed.

Summary event information can be viewed at the control front-panel LCD using the front-panel pushbuttons. Press the EVENTS/EVENTOS pushbutton (primary function) and the appropriate left/right and up/down pushbuttons (secondary function) to view event information.

If no parameters are issued with the EVE command, then you will automatically receive both the analog (A) and digital (D) sections of the event report.

Access Levels and Password Protection

Passwords Required With

Front-Panel Pushbuttons?

See Pushbutton Primary

Functions subsection in the


Issue serial port commands to the SEL-351P-3 to view metering values, change recloser control settings, obtain event information, etc. The available serial port commands are listed in Table 3. The commands can be accessed only from the corresponding access level as shown in the table, but a higher access level can access the serial port commands in a lower access level.

Access Level 0 (the lowest access level)

Access Level 1

Access Level E (EZ access level)

Access Level B

Access Level 2 (the highest access level)

As a security measure, entry to a particular access level (except Access

Level 0) requires a unique password. This allows the user to set up a password system to deny unqualified or unauthorized personnel access to higher levels.

The SEL-351P-3 ships from the factory with default passwords (see

Table 5). If restrictions are to be placed on personnel using the

SEL-351P-3, the factory default passwords must be changed. Make sure that password information is stored for future reference in the event that it is lost or forgotten.

Passwords may include up to six characters. Valid characters consist of:

‘A–Z’, ‘a–z’, ‘0–9’, ‘-’, and ‘.’. Upper- and lower-case letters are treated as different characters.

Disable Passwords

If you wish to disable password protection for a specific access level

(must be in Access Level 2), simply set the password to DISABLE (must


Communications be uppercase). For example, to disable the Access Level 1 password, type the following:

=>> PAS 1 DISABLE < Enter >

Password Disabled

=>>

The password protection for Access Level 1 is now disabled.

The following Password Jumper subsection describes how password protection for all access levels can be disabled by a hardware password jumper.

Password Jumper

!

CAUTION: The relay module contains devices sensitive to

Electrostatic Discharge (ESD).

When working on the relay module with front or top cover removed, work surfaces and personnel must be properly grounded or equipment damage may result.

This subsection provides instructions for putting the password jumper in place if you wish to operate the SEL-351P-3 without password protection or in the event that the passwords are lost or forgotten.

When the password jumper (JMP6-A) is ON (in place), password protection is disabled. Figure 15 shows the general location of the password jumper.

When the password jumper is OFF (removed/not in place), password protection is enabled. This is how the SEL-351P-3 ships from the factory.

Then the only way to disable password protection is with the PAS command (see preceding Disable Passwords subsection).

To change the password jumper position, carry out the following steps:

1.

De-energize the SEL-351P-3.

2.

Disconnect all connections to the SEL-351P-3 (remove GROUND last).

3.

Take SEL-351P-3 to an ESD (Electrostatic Discharge) protected work area.

4.

Remove eight Phillips-head screws from front and left side panel of

SEL-351P-3.

5.

Disconnect the ribbon cables from the front panel.

6.

Remove front panel of SEL-351P-3.

7.

Locate the jumper(s) to be changed (refer to Figure 15). Change the jumper position.

8.

Reconnect ribbon cables to front panel.

9.

Replace eight Phillips-head screws in front and left side panel of

SEL-351P-3 relay module.

10.

Reconnect all connections to the SEL-351P-3 (reconnect

GROUND first).

11.

Reenergize the SEL-351P-3.

Press the CLOSE/CIERRE operator control pushbutton to close the recloser. The corresponding RECLOSER

CLOSED/RESTAURADOR CERRADO LED illuminates to indicate the recloser is closed.

The CLOSE/CIERRE operator control pushbutton does not have to be continually pressed to allow for cold load pickup (i.e., disable fast curves, and desensitize delay curves and SEF element). There is automatic allowance for cold load pickup. See Cold Load Pickup

Scheme (No. 33) settings in the Settings section.

Option : Set a delay, so the operator can press the CLOSE/CIERRE operator control pushbutton and then move a safe distance away from the recloser before the SEL-351P-3 issues a close (the

CLOSE/CIERRE operator control comes with no set delay in the factory settings). With a set delay, press the CLOSE/CIERRE operator control pushbutton momentarily, and notice that the corresponding RECLOSER CLOSED/RESTAURADOR

CERRADO LED flashes on and off during the delay time, indicating a pending close. Abort the pending close by pressing the

CLOSE/CIERRE operator control pushbutton again or by pressing the TRIP/DISPARO operator control pushbutton. This delay setting for the CLOSE/CIERRE operator control is PB8D (range: 0 to 3600 cycles; factory-set at 0 cycles—no delay). The delay is set via the

SET G command (PB8D is not an EZ setting). See Section 1:

Factory-Set Logic in the SEL-351P-3 Instruction Manual for more information.

The reference to Settings Groups 1 and 2 at the top of Table 9 refers to the two choices for the active setting group:

Settings Group 1 = main settings

Settings Group 2 = alternate settings

Refer to the Operator Controls subsection in the Front-Panel Interface section (ALTERNATE SETTINGS/AJUSTES ALTERNATIVOS operator control pushbutton) for more information on how to switch between these two setting groups. In the factory EZ settings, these two setting groups are set the same (Settings Group 3 set the same, too—see side bar note).

The Global EZ settings at the end of Table 9 apply to both settings

Groups 1 and 2 (and Settings Group 3—see side bar note).

Those factory settings indicated with an asterisk (*) in Table 9 are hidden with these particular factory settings. As a general rule, if a main setting is set to N, then the subsettings that follow are hidden. The following

Settings Descriptions subsection explains the details behind hiding the settings. Complete setting ranges are also given in the Settings

Descriptions subsection.

!

WARNING: Anytime an EZ setting is changed, review all the EZ settings before enabling the new settings. Pay close attention in circumstances where a setting was once set to OFF or N and then later turned on (enabled)—other related settings may need to be turned on, though may still be set to OFF or N.

Reclose interval settings corresponds to the highest set Operations to lockout (No.

For example, if the highest set Operations to lockout setting is Operations to lockout - phase (No. 15) = 4, then settings Reclose interval 1 , Reclose interval 2 , and Reclose interval 3 are available (three reclose attempts). Because it is not available, Reclose interval 4 is hidden and set to zero (0).

The number of reclosing attempts (i.e., available Reclose interval settings) is always one less than the number of trip operations (e.g., 4 “trips” – 1 = 3 “reclosures”).

Reset time from lockout setting is set shorter than the Reset time for auto reclose setting.

The Close power wait time setting is a time window that starts timing after a reclose interval times out.

During this time window, the SEL-351P-3 checks the trip and close capacitors connected to it:

• If the trip and close capacitors are charged, this indicates that the close power for the recloser is present, and reclosing proceeds.

Figure 18 and Figure 19 show the front-panel trip-latched LEDs. They are: TRIP/DISPARO, FAST

CURVE/CURVA RAPIDA, HIGH CURRENT/ALTA CORRIENTE, UNDER FREQ./BAJA FREC., and all

FAULT TYPE/TIPO DE FALLA LEDs.

These LEDs latch in at the rising edge of trip and remain illuminated—even after power is turned off and then on again.

Reset trip-latched LEDs on close = Y or Y1:

The trip-latched LEDs extinguish automatically when the recloser closes.

Reset trip-latched LEDs on close = N or N1:

The trip-latched LEDs extinguish automatically (or are newly latched in) when the SEL-351P-3 trips again.

Settings options Y1 and N1 disable the embedded 3-second qualifying time delay on the LOCK operator control (see the Operator Controls subsection in the Front-Panel Interface section). In this mode, the LOCK operator control effectively operates as the other operator controls, with no time delay.

51 SF6 low pressure warning threshold in atm.


1.1 0.9–2.0 atmospheres 0.1

The SF6 gas pressure inside the GVR recloser is typically at 1.3 atmospheres (atm). If the pressure goes below the SF6 low pressure warning threshold, then the ALARM output contact pulse for 5 seconds. The present SF6 gas pressure can be accessed with the STATUS command (see Table 3 in the Communications section).

Pressure sensing in the SEL-351P-3 has a 5-minute time constant with a 95 percent response. For example, if the SF6 gas pressure is suddenly lost and recloser tank pressure goes from 1.30 atm. to atmospheric pressure

(1.00 atm), after 5 minutes the SEL-351P-3 reports the SF6 gas pressure at around:

1.30 – 0.95 • (1.30 – 1.00) = 1.02 atm

Read and understand preceding sections so that the SEL-351P-3 can be safely grounded, powered up, and set. Especially understand the

Installation section.

Testing the SEL-351P-3 Without Regularly Installed Apparatus

Observe Recloser Count

Sequencing During Testing:

See Pushbutton Primary

Functions subsection in the

Front-Panel Interface section

(OTHER/VARIOS pushbutton—select "79").

Refer to Figure 12 and Figure 13 in the Installation section. If the regularly installed apparatus outside the SEL-351P-3 (i.e., the recloser, the external capacitor circuitry, and batteries) is not available during testing, then some settings and connections changes have to be made to compensate.

Logic Settings Changes

Refer to the SEL-351P-3 Instruction Manual , Section 10: Serial Port

Communications and Commands , specifically the SHO and SET commands. Factory default logic settings are listed under the SHO L command. Make the following logic settings changes with the SET L command:

* CL = (PB8*!LT5+CC*LT5+/IN102*LT5)*LT6

[normal setting is:

CL =

(PB8*!LT5+CC*LT5+/IN102*LT5)*LT6*TRCAP*CLCAP]

The dependence on the trip and close capacitors is removed as a requirement to issue a front panel close via the CLOSE/CIERRE operator control or via the serial port close command. See the

Close Logic subsection in Section 1: Factory-Set Logic in the

SEL-351P-3 Instruction Manual for explanation about the CL logic setting.

* 79CLS = 1

[normal setting is:

79CLS = TRCAP*CLCAP*!BADBAT*!DTFAIL]

The dependence on the trip and close capacitors and the batteries is removed as a requirement to issue an auto-reclose. See the

Reclose Supervision Logic subsection in Section 1: Factory-Set

Logic in the SEL-351P-3 Instruction Manual for explanation about the 79CLS logic setting.

Important: When testing is finished, return these settings back to normal.

Battery Operation Overview

Battery Connections:

Connect a 24 volt lead-acid battery to terminals 6 (+) and

2 (–) of POWER connector J6

(see Figure 12 ).

When ac power is interrupted to the SEL-351P-3, a 24 volt lead-acid battery supplies power to the SEL-351P-3.

The battery discharges to keep the SEL-351P-3 operating until any of the following occur:

• AC power is restored (the SEL-351P-3 continues to operate and the battery starts charging again)

• A battery discharge time limit is reached, the battery is automatically disconnected internally, and the SEL-351P-3 turns off (see following settings discussion)

• A battery discharge voltage limit is reached, the battery is automatically disconnected internally, and the SEL-351P-3 turns off (see following settings discussion)

After the SEL-351P-3 turns off, it wakes up if any of the following occur:

• AC power is restored

• The WAKE UP/DESPERTAR operator control is pressed and the

24 volt battery is reconnected internally

Battery-Related Settings

The following four battery-related settings are made with the SET FZ

(global EZ settings) command:

• Battery Amp-hours (6.5–20.0)

• Power-off Delay After AC Loss (OFF, 1–1440 min)

• Power-off Delay After Wake Up (OFF, 1–1440 min)

• Power-off Voltage Level 1 (19.2–24Vdc)

See the Settings section for explanations and default settings.

Battery Status

Review May be Necessary:

This battery test section makes use of front-panel pushbuttons and serial port commands.

Review the Communications and Front-Panel Interface sections if needed.

Was It a Load Test Failure?

If the BATTERY PROBLEM/

BATERIA PROBLEMA LED is illuminated and MODE doesn’t display BADBAT, then the battery failed the latest load test. See the following Load

Test subsections.

The status of the battery can be checked via the front panel or serial port.

Battery Status via Front Panel

The BATTERY PROBLEM/PROBLEMA BATERIA LED illuminates for any of the following battery problems:

* Load test failure

* Damaged (battery cannot charge)

Press the STATUS pushbutton on the front panel of the SEL-351P-3 to access more battery status information. With the secondary function up/down arrow pushbuttons, move to different status screens. Those of interest for the battery are listed in Table 12.

Battery Status via Serial Port

Execute the STATUS command, and have the same information available via the preceding front-panel STATUS/DIAGNO pushbutton.


Battery

Automatic Battery Load Test

The SEL-351P-3 automatically load tests the 24 V battery about every 24 hours.

An internal 24-hour timer cumulatively times whenever the SEL-351P-3 is in the charge mode (120 Vac is powering the SEL-351P-3 and charging the battery; charge rate is 100 mA or less). Even if the battery is fully charged (and not discharging), the SEL-351P-3 is still in the charge mode.

After the 24-hour timer times out (and the SEL-351P-3 is still in the charge mode), an internal 1 Amp load is automatically paralleled with the battery for as many as 5 seconds. If battery voltage drops below 22.0 V during this load test, the test stops and the BATTERY

PROBLEM/PROBLEMA BATERIA LED illuminates and stays illuminated until the next battery test is successful. This load test failure condition can be routed to an output contact if desired (see the Battery

System Monitor subsection in Section 8 of the SEL-351P-3 Recloser

Control Instruction Manual ).

Battery test state is: OK/FAILED

The periods appear on each consecutive line as each second of the fivesecond battery load test times. At the end of the test, OK or FAILED is displayed. If the battery fails the 1 Amp load test (same criteria as described previously in Automatic Battery Load Test ), the BATTERY

PROBLEM/PROBLEMA BATERIA LED illuminates and stays illuminated until the next battery load test is successful. This load test failure condition can be routed to an output contact if desired (see the

Battery System Monitor subsection in Section 8 of the SEL-351P-3

2.

Execute the BTT command to see how much time remains until the next automatic battery discharge test. If the battery is okay (it is charging or discharging), the following message is displayed:

Battery test state is: OK/FAILED Time until next battery test:

XX.X hours

The “next battery test” is the automatic load test described previously in

Automatic Battery Load Test .

Value XX.X gives time until the next battery test to the nearest tenth of an hour. If 24+ is displayed for value XX.X, this infers an indeterminate amount of time until the next automatic load test (the battery is either discharging or it is charging at a rate greater than 100 mA).

Panacea and Amazon

Recloser Controls Are

Essentially the Same:

Panacea and Amazon

Recloser Controls are essentially the same, just different front-panel panel labeling/language. These recloser controls are also referred to as the SEL-351P-2

Recloser Control (or the older

SEL-351P-1 or SEL-351P

How the SEL-351P-3

Recloser Control Differs

From the Panacea and

Amazon Recloser Controls:

• Powered by AC power

(read this Appendix) instead of DC power.

• Battery charger is constantvoltage, not constant current (changes in batterrelated settings, too—see

Battery section.

• Various voltage and current options (see Table 1).

Panacea or Amazon Recloser Controls can be replaced with the

SEL-351P-3 Recloser Control, but accommodation has to be made to power the SEL-351P-3 Recloser Control with AC power (see Power

Supply Range in the Specifications section). The AC power connection details are given in this section. No other changes have to be made. The

DC voltage that powered Panacea or Amazon Recloser Controls (via terminals 16 and 9 of CONTROL connector J5) is still connected up to the SEL-351P-3 Recloser Control, but this DC voltage no longer provides power to the SEL-351P-3 Recloser Control (see Figure 13).

Near the top of Figure 3 (and Figure 4 through Figure 8—see Table 1 for

SEL-351P-3 Recloser Control model differences), notice the new addition of the POWER IN connector J7 on the SEL-351P-3 Recloser Control

(compared to Panacea or Amazon Recloser Controls)—this is where AC power is connected. See the Power Supply Connection side bar note accompanying Figure 12 and note the internal connection of POWER IN connector J7 (terminals 1 and 2) and POWER connector J6 (terminals 4 and 8) shown in Figure 12. Connecting AC power to POWER IN connector J7 (terminals 1 and 2) will “heat up” POWER connector J6

(terminals 4 and 8). In existing Panacea or Amazon Recloser Control cabinets, no connection is made to terminals 4 and 8 of POWER connector J6. Thus, terminals 4 and 8 of POWER connector J6 remain effectively unused in this recloser control replacement process.

Steps for Recloser Control Replacement

1.

Verify the cabinet (containing the Panacea or Amazon Recloser

Control) is properly grounded.

2.

De-energize the entire cabinet for the Panacea or Amazon Recloser

Control, including the incoming AC power.

3.

Remove the side panel connections to the Panacea or Amazon

Recloser Control. Remove the side panel GROUND connection last.

4.

Remove the Panacea or Amazon Recloser Control from the cabinet swing panel.

5.

Find the existing connector for AC power in the rear of the cabinet

(see Figure 23). Trace the existing wiring to this existing connector and confirm that it brings in AC power from outside the cabinet.

These existing wires should already be completely de-energized, per previous steps.



The existing connector shown in Figure 23 could possibly differ in type and wiring connections.

Consult with the cabinet manufacturer.

6.

Remove this existing connector in Figure 23 from its mating connector in the rear of the cabinet.

7.

If not already tagged for identification, tag the existing Line (Hot) and Neutral wires shown in Figure 23.

8.

Remove the existing Line (Hot) and Neutral wires from the existing connector in Figure 23. Do not remove the existing Ground wire.

9.

Figure 24 shows cable C5586 which will bring AC power from the existing connector in the rear of the cabinet to the SEL-351P-3

Recloser Control.

10.

Carefully install the blade for the white wire of cable C5586 into the Neutral wire position of the existing connector, along with the existing Neutral wire. Place the blade (white wire) to allow maximum room for reinstalling the existing Neutral wire. Tighten the combination of blade (white wire) and existing Neutral wire, following the tightening torque recommendations of the cabinet manufacturer.

11.

Carefully install the blade for the black wire of cable C5586 into the Line (Hot) wire position of the existing connector, along with the existing Line (Hot) wire. Place the blade (black wire) to allow maximum room for reinstalling the existing Line (Hot) wire.

Tighten the combination of blade (black wire) and existing Line

(Hot) wire, following the tightening torque recommendations of the cabinet manufacturer.

12.

The resultant wiring on the existing connector should now appear as the top portion of Figure 25 (cable C5586 is not yet connected to the SEL-351P-3 Recloser Control).

13.

Reconnect this rewired existing connector to its mating connector in the rear of the cabinet.

14.

Install the SEL-351P-3 Recloser Control on the cabinet swing panel.

Make the GROUND connection on the SEL-351P-3 Recloser Control side panel. Do not make any other connections yet.

Route cable C5586 so that it makes a sensible path to the swing panel and can be connected to POWER IN connector J7 on the SEL-351P-3

Recloser Control (do not make any connection yet). Use wire ties to fix cable C5586 in place enroute. Make allowance for the transition to the swing panel, so that cable C5586 does not become pinched, strained, or otherwise damaged at the swing panel hinge transition. Do not connect cable C5586 to the SEL-351P-3 Recloser Control yet.

15.

Re-energize the cabinet, including the incoming AC power.

16.

Make any necessary measurements, including the AC voltage on the cable C5586 connector, verifying its adequacy (see Power

Supply Range in the Specifications section).



17.

If the SEL-351P-3 Recloser Control has not been set yet, connect cable C5586 to POWER IN connector J7 on the SEL-351P-3

Recloser Control side panel as shown in the bottom portion of

Figure 25 (skip to the next step if settings have already been made).

The connector clip on cable C5586 will positively lock in place on

POWER IN connector J7. Do not make any other connections yet.

In a few seconds, the CONTROL ENABLED/CONTROL

HABILITADO LED and the AC SUPPLY/ALIM CA LED will illuminate. See the Low Capacitor Voltage Alarm on Display side bar note accompanying Figure 16. Make settings. When finished making settings, disconnect cable C5586 from POWER IN connector J7 on the SEL-351P-3 Recloser Control side panel, entirely de-energizing the SEL-351P-3 Recloser Control.

18.

Reconnect the power system current and voltage to the respective

CURENTS and VOLTAGES connectors on the SEL-351P-3

Recloser Control side panel (see Table 1 for various voltage and current options). Then, reconnect CONTROL connector J5 and

POWER connector J6. The SEL-351P-3 Recloser Control should still be de-energized.

19.

Connect cable C5586 to POWER IN connector J7 on the

SEL-351P-3 Recloser Control side panel as shown in the bottom portion of Figure 25. The connector clip on cable C5586 will positively lock in place on POWER IN connector J7. In a few seconds, the CONTROL ENABLED/CONTROL HABILITADO

LED and the AC SUPPLY/ALIM CA LED will illuminate. See the

Low Capacitor Voltage Alarm on Display side bar note accompanying Figure 16.

20.

Perform any other necessary commissioning.
