Only settings such as minimum trip pickup, curve type, and reclose interval are necessary. These settings are made at an EZ (easy) access level. SELOGIC control equations cannot be changed at this access level. Control logic is preconfigured at the factory. To customize the logic for advanced functions, the SELOGIC control equations must be reprogrammed. Reclosing The SEL-351R Falcon can reclose as many as four (4) times. This allows as many as five (5) operations of any combination of fast and delay curve overcurrent elements. Each reclose interval can be set for as many as 999,999 cycles (more than 4.5 hours), if necessary. After a reclose interval has timed out, the control waits a user-set time (close power wait time) for the presence of adequate Vac power before proceeding with the auto reclose. The recloser needs either primary or secondary voltage to provide the closing power, depending on how SEL-351R Falcon Data Sheet the recloser is equipped. The Vac power into the SEL-351R Falcon is an indication of the presence of this primary or secondary voltage. The close power wait time has the same 999,999-cycle setting range as the reclose interval. The reset times are set separately for reset timing for an auto reclose and reset timing for a manual/remote close from lockout. Traditionally, the reset time for a manual/remote close from lockout is set for less than the reset time for an auto-reclose. The reset times have the same 999,999-cycle setting range. Front-panel LEDs track the CONTROL STATE for auto-reclosing: RESET, CYCLE, or LOCKOUT (see Figure 14 and Table 4). Sequence coordination logic is enabled to prevent the SEL-351R Falcon from tripping on its fast curves for faults beyond a downstream recloser. Customize reclosing logic by using SELOGIC control equations. Use programmable counters, latches, logic functions, and analog compare functions to optimize control actions.

The US and IEC curves conform to IEEE C37.112-1996 IEEE Standard Inverse-Time Characteristic Equations for Overcurrent Relays. The traditional recloser curve choices listed in Table 1 use the older electronic control designations. The SEL-351R Falcon also works with the newer microprocessor-based control designations.

For a nominal recloser CT ratio of 1000:1, these curves can be set as sensitive as 50 A and 5 A primary for phase and ground overcurrent protection, respectively. Traditional recloser curve A and 101 are the same curve. Use either designation in making curve settings in the SEL-351R Falcon. Four (4) user-designed curves (created with a software package) can be downloaded to the SEL-351R Falcon. The fast and delay curves (phase or ground) can be set with the user-designed curves or the curve choices in Table 1. Modify fast and delay curves (including US or IEC curve choices) with the following traditional recloser control curve modifiers: ➤ constant time adder—adds time to curve ➤ vertical multiplier (time dial)—shifts whole curve up or down in time ➤ minimum response time—holds off curve tripping for minimum time ➤ high-current trip—instantaneous trip with optional time delay ➤ high-current lockout—high-set lockout threshold Front-panel target LEDs indicate any overcurrent trip in general (TRIP LED) and then discriminate a fast-curve trip (FAST CURVE LED) or a high-current trip (HIGH CURRENT LED).

One choice resets the elements if current drops below pickup for at least one cycle. The other choice (for US or IEC curves only) emulates electromechanical induction disc elements, where the reset time depends on the time-dial setting, the percentage of disc travel, and the amount of current. Sensitive Earth Fault (SEF) Element A sensitive earth fault (SEF) element with time delay (as long as 16,000 cycles) can be set as sensitive as 5 A primary (assuming nominal recloser CT ratio of 1000:1). Current channel IN with a 0.05 A secondary nominal rating provides this sensitivity (see Figure 15). The front-panel SEF LED indicates any SEF element trip (see Figure 14 and Table 4). Custom Overcurrent Protection Customize the overcurrent protection by reprogramming the corresponding SELOGIC control equations. Metering and Monitoring Complete Metering Capabilities The SEL-351R Falcon provides extensive and accurate metering capabilities. See Specifications on page 17 for metering and power measurement accuracies. Table 2 Metered quantities include phase voltages and currents (including demand currents); sequence voltages and currents; power (including demand), frequency, and energy; and maximum/minimum logging of selected quantities (see Table 2). The recloser control reports all metered quantities in primary quantities (current in A primary and voltage in kV primary). Meteringa Quantities Description Currents IA,B,C,N, IG Input currents, residual ground current (IG = 3I0, IA + IB + IC). Voltages VA,B,C, VS Wye-connected voltage inputs, synchronism-check voltage input. Power MWA,B,C,3P , MVARA,B,C,3P Single- and three-phase megawatts and megavars. Energy MWhA,B,C,3P , MVARhA,B,C,3P Single- and three-phase megawatt-hours and megavar-hours. Power Factor PFA,B,C,3P Single- and three-phase power factor; leading or lagging. Sequence I1, 3I2, 3I0 Positive-, negative-, and zero-sequence currents. Frequency, FREQ (Hz) Instantaneous power system frequency (monitored on channel VA). a If true three-phase voltage is not connected, the voltage (VA,B,C) uses phantom voltages derived from a single-phase voltage to calculate MW/MVAR, MWh/MVARh, and power factor metering values. Recloser Wear Monitor Reclosers suffer mechanical and electrical wear every time they operate. The recloser wear monitor measures unfiltered ac current at the time of trip and the number of close-to-open operations as a means of monitoring this wear. Every time the recloser trips, the recloser control records the magnitude of the raw current in each phase. This current information is integrated on a per-phase basis. When the result of this integration exceeds the threshold the recloser wear curve establishes, the SEL-351R Falcon asserts a logic point for the affected phase. This logic point can be routed for alarming or to modify SEL-351R Falcon Data Sheet reclosing (e.g., shorten the number of reclosures). This method of monitoring recloser wear is based solidly on methods of breaker rating from breaker manufacturers. Figure 4 shows three setpoints necessary to emulate a breaker wear curve. Program the setpoints in Figure 4 to customize the recloser wear curve. The SEL-351R Falcon sets setpoints automatically according to recommendations for reclosers in ANSI C37.61-1973. Only the recloser type (oil or vacuum) and the interrupt rating are necessary settings.

The fault locator uses fault type, replica line impedance settings, and fault conditions to develop an estimate of fault location without communications channels, spe- cial instrument transformers, or prefault information. This feature contributes to efficient dispatch of line crews and fast restoration of service. The fault locator requires three-phase voltage inputs.

The system automatically checks interrelated settings and highlights out-of-range settings. Transfer the settings created off-line to the SEL-351R Falcon using a PC communications link. The software converts event reports to oscillograms with time-coordinated element assertion and phasor/sequence element diagrams. The ACSELERATOR QuickSet interface supports Microsoft® Windows® operating systems. View real-time phasors via ACSELERATOR QuickSet. Figure 6 QuickSet Designer® SEL-5031 Software additionally allows users to create personalized Application Designs. Use Application Designs within ACSELERATOR QuickSet Designer to quickly implement advanced schemes such as automatic network reconfiguration. Application Designs hide settings you do not want changed (e.g., SELOGIC control equations), while making visible the minimum necessary settings (e.g., timer and pickup settings) to implement the scheme. You can alias and manipulate mathematically all settings for simple end-user interfacing. You can also define custom notes and settings ranges. Application Designs enhance security by allowing access to only a specified group of settings. Create Application Designs that include the most commonly used relay features and settings for your system (see Figure 6) and watch commissioning times drop drastically.

With MIRRORED BITS operating on two serial ports, there is communication upstream and downstream from the SEL-351R Falcon site. The SEL-patented MIRRORED BITS communications technology provides bidirectional relay-to-relay digital communication. MIRRORED BITS can operate independently on as many as two EIA-232 serial ports on a This bidirectional digital communication creates eight additional virtual outputs (transmitted MIRRORED BITS) and eight additional virtual inputs (received MIRRORED SEL-351R Falcon Data Sheet Schweitzer Engineering Laboratories, Inc. 9 BITS) for each serial port operating in the MIRRORED BITS mode (see Figure 10). Use these MIRRORED BITS to transmit/receive information between an upstream relay and a downstream recloser control to enhance coordination and achieve faster tripping for downstream faults. MIRRORED BITS technology also helps reduce total scheme operating time by eliminating the need to assert output contacts to transmit information. SEL-351S Relay TMB1 Transmit TMB2 . .

Receive RMB8 MIRRORED BITS Transmit and Receive Bits Advanced SELOGIC Control Equations Advanced SELOGIC control equations allow you to assign relay outputs to any logical combination of Relay Word elements or inputs. Program SELOGIC control equations by combining relay elements, inputs, and outputs with SELOGIC control equation operators. Bits in a table called the “Relay Word” reflect the state of all logical elements in the recloser control. These logical elements include all current (50/51) and directional-level detecting elements, timer elements, SELOGIC control equation variables, inputs, outputs, and remote, local, and latched bits. SELOGIC control equation operators include OR, AND, invert, parentheses, and rising and falling edges of element state changes. Analog compare functions (<, >, =, < >) are also available. These functions add control flexibility to customize logic based on recloser shot count or other control values. The basic building blocks of SELOGIC control equations are the Relay Word bits. The Relay Word bits are simple digital quantities having a logical value of either 0 or 1. The terms “assert” or “asserted” refer to a Relay Word bit that has a value of 1 or is changing from 0 to 1. The terms “deassert” or “deasserted” refer to a Relay Word bit that has a value of 0 or is changing from 1 to 0. Various elements within the recloser control assert or deassert Relay Word bits. Use these elements in the fixed internal logic of the recloser control to make decisions, to interpret inputs, or to drive outputs. These bits are available so that you can exercise flexibility in defining inputs or outputs, in specifying control variables for internal logic, or in creating special customized logic through the use of SELOGIC control equations. In addition to Boolean logic, 16 general purpose SELOGIC control equation timers eliminate external timers for custom protection or control schemes. Each timer has independent time-delay pickup and dropout settings. Program each timer input with any element (e.g., time qualify a voltage element) you specify. Assign the timer output to trip logic, transfer trip communications, or other control scheme logic. The SEL-351R Falcon has the same SELOGIC control equations capability as the established SEL-351R-2. Hardware Overview The convenient side-panel construction of the SEL-351R Falcon provides easy access to all controls and connections. Communications ports, contacts, and control cable connection points are all readily available. Labeling is shown in Figure 14 (right-hand side). i4422b Figure 11 SEL-351R Falcon Module Side Panel Schweitzer Engineering Laboratories, Inc. SEL-351R Falcon Data Sheet 10 NEMA Type 3R (IP32) Enclosure Recloser Control Connections Available in Lift-To-Open (Figure 16) and Swing-Open (Figure 17) enclosure options. Terminals The control cable from the recloser attaches at the bottom of the SEL-351R Falcon enclosure to a standard receptacle. The wiring from this receptacle continues into the control itself, with the currents and control landing on the side-panel terminals. Mount user-supplied accessory panel Mount SEL-2401 and/or SEL-3022 Relay Module The 120 or 230 Vac power parallels voltage channel V1, as shown in the retrofit of a traditional installation in Figure 13. If you order the SEL-351R Falcon with additional voltage channels V2, V3, and VS, connect true three-phase voltage and synchronism-check voltage to the side-panel terminals. An internal battery monitor/charger provides battery charging/discharging. Through this battery monitor/charger the SEL-351R Falcon can monitor battery voltage. The SEL-351R Falcon puts itself to sleep if voltage falls to a user-set threshold (or if a user-set timer times out) after an extended outage. Batteries The SEL-351R Falcon can also be powered with 125 Vdc or 250 Vdc.
