Additional tests/observations may be performed during witness testing. Note 1: All current, voltage, and signal inputs/outputs shall be connected or measured at terminal strips or fuses where the District will land field wiring. This is to ensure the correct operation of the entire circuit path. Note 2: Tests that generate a signal to remote equipment will be designated with a (*). These tests will be deemed valid if signal is received at terminal strip as indicated in Note 1. Note 3: Any indicated pickup values are secondary values seen by the relays unless noted otherwise. The purpose of this is to verify operation, not to verify timing. Therefore no time delays (adders, multipliers, etc.) are included in this test plan. Note 4: Manufacturer will need to provide AC and DC station service for testing. AC station service shall be connected in on both incoming lugs of the transfer switch. Test wiring shall be routed such that safe operation of the AC transfer switch is not impeded. DC station service shall be connected in at the DC connection lugs provided under section 10.1.c.i. Note 5: Testing shall include pulsing SCADA open/close commands via the relay HMI to verify jumper modifications have been completed. Confirm SCADA jumper has been properly set in relays prior to District’s arrival. General Items: 1) Door hardware matches specification and doors operate smoothly. 2) No signs of damage to structure. 3) General Workmanship: a. Cable routing, securement, etc. b. Compartment doors match provided equipment layouts. c. Labeling (conductors, equipment, etc.) d. Minimum quantities of conduits and knockouts are installed. 4) Verify operation of “Bug-Eye” emergency lights by shutting off breaker. 5) Verify operation of 240V AC station service transfer switch. a. Manufacturer will need to energize both sides of AC transfer switch for test. It is acceptable to energize both sides using the same source circuit. 6) Verify station service loss of AC and loss of DC relays are functioning (measure at terminal strip in Aux. Compartment). 7) Verify Feeder loss of DC relays are functioning (measure at terminal strip in Aux. Compartment). 8) Verify DC Panel Schedule. Benton PUD - 34 - Specification 2024-01 Revised 2/8/2024 9) Verify AC Panel Schedule. 10) Verify operation of V5B, V6B, V7B, V8B transfer switches. 11) Verify incoming bus phasing matches specification. 12) Verify outgoing bus phasing matches specification. 13) Verify operation of Breaker Remote Racking system on each breaker. Bay Protective Equipment Functional Testing (SEL-787, SEL-751A, 86 Relay): Open/Close Tests: 1) Circuit Switcher Control Switch Opens/Closes Circuit Switcher (*). 2) Circuit Switcher Control Switch Red & Green lights work. 3) Circuit Switcher Control Switch Latch inhibits Circuit Switcher closing (*). a. This test is completed by latching control switch and then pulsing a “close command” from the SEL-751A to mimic a SCADA command. b. Output contact from SEL-751A should not close. Trip Tests: 1) 787 Relay trips 86 relay. 2) 787 Relay trips Circuit Switcher directly (*). 3) 751 Bay Relay trips 86 relay. 4) 751 Bay Relay trips Circuit Switcher directly (*). 5) 63X input trips 86 relay 6) 86 relay trips Circuit switcher (*). 7) 86 relay trips V5B, V6B, V7B, V8B. Block Closing: 1) With 86 Relay in trip position perform the following tests: a. Circuit Switcher control switch handle will not close Circuit Switcher (*). b. V5B, V6B, V7B, or V8B control switches will not close feeder breakers. c. SCADA command will not close circuit switcher (*). d. SCADA command will not close V5B, V6B, V7B, or V8B (*). Feeder Protective Equipment Functional Testing (V5B, V6B, V7B, V8B): 1) Trip feeder relay with reclosing enabled. 2) Verify that LTC block opens during reclose cycle open interval and closes when breaker closes back in. 3) Do not reset 79 element. Trip feeder relay again with reclosing enabled, verify relay locks out. 4) Verify that LTC block remains closed after lockout trip. 5) Feeder Pushbuttons Opens/Closes Breaker and Red/Green lights work accordingly.
