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:
10
SEL-351P-3 Recloser Control Quick-Start Installation and User’s Guide
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.

SEL-351P-3 Recloser Control Quick-Start Installation and User’s Guide
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.

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 #632 bolt or mounting stud, with lock nuts is recommended.
Wire Harness Mounting
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.

Current and Voltage Connections
See Table 1 for all voltage and
current options/ratings.
Frequency Measurement
Voltage input V1 (VOLTAGES
connector) also provides the
frequency measurement (e.g.,
for underfrequency load
shedding).
18
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.
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.

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
24 Vdc Battery
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.
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.

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 AutoReclosing
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.
Boost Power Switch
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.
20
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
SEL-351P-3 Recloser Control Quick-Start Installation and User’s Guide
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.

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.
22
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).

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.
Terminal Emulation
Programs:
Examples of PC-based
terminal emulation programs
include: ProComm Plus®,

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

Event Reports
Note:
The event report length is
selectable: 15 or 30 cycles.
More options are available to
customize event reports.
Refer to Section 12 in the
SEL-351P-3 Instruction
Manual for more event
information.
Event reports are automatically triggered at the beginning of a fault and
when the SEL-351P-3 issues a trip. Event report length is 15 cycles
(factory default). The latest twenty-eight 15-cycle event reports are stored
in nonvolatile memory.
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 ]
SEL-351P-3 Recloser Control Quick-Start Installation and User’s Guide
31
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:
Parameter
Event Report Parameters
Description
n
Choose event number (1–28). Defaults to 1 if not
specified.
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
Front-Panel Interface section.
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.

After entering new passwords, type PAS<Enter> to inspect them. Verify
they are what you intended, and record the new passwords.
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
SEL-351P-3 Recloser Control Quick-Start Installation and User’s Guide

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
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.
!
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.
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.

curve choices:
•
Recloser Curves (see Table 7)
•
US Curves (see Table 8)
•
IEC Curves (see Table 8)
•
User-Programmable Curves (see Table 8)
The recloser curves in Table 7 show both the older electronic control
designation and the newer microprocessor-based control designation. The
recloser curves can be specified in a curve setting using either designation.
For example, a given traditional recloser curve has the following two
designations:
Older electronic control designation:
A
Newer microprocessor-based control designation:
101
Traditional recloser curve A and curve 101 are the same curve—use
either designation in making curve settings in the SEL-351P-3.

The SEL-351P-3 ships with the factory EZ settings shown in Table 9.
The corresponding number references provide a quick way to find the
settings (or subsettings) in the Settings Descriptions subsection that
follows.
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.

The Min. trip - phase setting determines the minimum phase current threshold for overcurrent detection

The displayed Amps primary setting range for Min. trip - phase is calculated by multiplying the effective
Amps secondary range [0.10 to 3.20] by the CT Ratio (No. 3) [400.0]:
(0.10 to 3.20) • 400.0 = 40.00 to 1280.00 range (Amps primary)
If the CT Ratio setting changes, the displayed Amps primary setting range for Min. trip - phase changes
accordingly. Due to processor calculations and rounding techniques, displayed range numbers may appear
slightly different than expected (e.g., 1279.99 instead of 1280.00).

The Min. trip - ground setting determines the minimum ground current threshold for overcurrent
detection in primary amps.
The displayed Amps primary setting range for Min. trip - ground is calculated by multiplying the effective
Amps secondary range [0.005 to 3.20] by the CT Ratio (No. 3) [400.0]:
(0.005 to 3.20) • 400.0 = 2.00 to 1280.00 range (Amps primary)
If the CT Ratio setting changes, the displayed Amps primary setting range for Min. trip - ground changes
accordingly. Due to processor calculations and rounding techniques, displayed range numbers may appear
slightly different than expected (e.g., 1279.99 instead of 1280.00).
If Min. trip - ground is effectively set <0.1 Amp secondary (e.g., for CT ratio [No. 3] = 400.0, Min. trip ground <40.00 Amps primary), then the corresponding curves flatten out above 1.5 Amps secondary (e.g.,

Amps secondary range [0.005 to 1.500] by the CT Ratio (No. 3) [400.0]:
(0.005 to 1.500) • 400.0 = 2.00 to 600.00 range (Amps primary)
If the CT Ratio setting changes, the displayed Amps primary setting range for Min. trip - ground changes
accordingly. Due to processor calculations and rounding techniques, displayed range numbers may appear
slightly different than expected (e.g., 599.99 instead of 600.00).

The Reclose interval settings (1 through 4) are each successively and individually timed. Reclose interval
timing cannot proceed until the following two conditions are met:
•
The trip condition has gone away.
•
The recloser has opened.
At the end of a reclose interval, an auto reclose attempt is made.
The number of available Reclose interval settings corresponds to the highest set Operations to lockout (No.
15, 16, or 17) setting.
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

lockout setting qualifies a manual/remote close of the recloser from the lockout state. Traditionally, the
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.
•
If the trip and close capacitors are not charged, this indicates that the close power for the recloser is not
present and reclosing is stalled. If the trip and close capacitors are not charged throughout the time
window, reclosing is aborted at the end of the time window, and the SEL-351P-3 goes to the lockout
state.
The 24 Vdc battery also has to be connected and healthy in order for reclosing to proceed.
•
If Close power wait time is set to 0 cycles, then the SEL-351P-3 makes only one check for charged trip
and close capacitors, after a reclose interval times out.

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

TESTING
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:
•

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 Load Test via Front Panel
1. Press the OTHER/VARIOS pushbutton on the front panel of the
SEL-351P-3.
A new screen appears, with BTT (battery test) as one of the
choices.
2. With the arrow pushbuttons, move the underscore to BTT.
3. To test the battery, press the SELECT/ACEPTAR pushbutton. The
battery load test proceeds, and the following message is displayed:
Testing Battery
. . . . . OK/FAIL
The periods on the second line appear consecutively as each second of the
five-second load test times by. At the end of the test, OK or FAIL 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 Battery
System Monitor in Section 8 of the SEL-351P-3 Recloser Control
Instruction Manual).

displayed:

.
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
Recloser Control Instruction Manual).
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).

SEL-351P-3 Recloser Control Quick-Start Installation and User’s Guide
APPENDIX B: Replace Existing Panacea or Amazon Recloser Controls With the SEL-351P-3 Recloser Control
APPENDIX B: REPLACE EXISTING PANACEA OR
AMAZON RECLOSER CONTROLS WITH THE SEL-351P-3
RECLOSER CONTROL
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.

APPENDIX B: Replace Existing Panacea or Amazon Recloser Controls With the SEL-351P-3 Recloser Control
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).

APPENDIX B: Replace Existing Panacea or Amazon Recloser Controls With the SEL-351P-3 Recloser Control
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.
