Description
GE General Electric Technical Specifications: IS200VTURH2B
Test Connections per Figure 17–2: RELAY TEST WIRING – DELTA CONNECTION on page 17–4.
A negative sequence voltage can be created by injecting a single phase-phase voltage, or a set of two phase
IS200VTURH2B phase voltages with a known negative sequence component. For a single phase-phase injection the negative
sequence voltage magnitude is the injected voltage divided by √3.
IS200VTURH2B Pickup
- Inject a negative sequence voltage = 0 into the bus voltage input of the relay. The PICKUP indicator should
be off.
- Slowly raise the voltage until the PICKUP indicator comes on. This is the pickup level.
- Lower the voltage until the PICKUP indicator goes out. This is the reset voltage, which should be 2% of VT
less than the pickup level.
Indications and Operations are as outlined under Phase Time Overcurrent 1.

IS200VTURH2B Blocking From Logic Inputs:
- Inject voltage to cause a pickup.
- Assert a logic input to provide a “Block Neg Seq Voltage”. The PICKUP indicator should immediately go
out.
- Repeat steps 1 and 2 for logic input “Block 1 TRIP Relay” as required.
IS200VTURH2B Timing:
- Connect the “Stop Trigger.”
- Set the voltage source to the required test voltage, then turn off the voltage.
- Reset the timer. Turn the voltage on and measure the operating time. Repeat steps 2 and 3 four more
times and obtain an average of the time intervals.
- Reset the relay and disconnect the “Stop Trigger.
Test Connections per Figure 17–1: RELAY TEST WIRING – WYE CONNECTION on page 17–4.
Pickup with One Phase For Operation:
- Inject Van = Vbn = Vcn = nominal voltage into the bus voltage input of the relay. The PICKUP indicator
should be off.
- Slowly lower Van until the PICKUP indicator comes on. This is the pickup voltage.
- Continue to lower Van until the PICKUP indicator goes out. This is the programmed Minimum Operating
Voltage level minus 2% of VT.
- Raise Van until the PICKUP indicator comes on, and continue to increase until the indicator goes out. This
is the reset voltage, which should be the pickup value plus 2% of VT.
- Repeat steps 1 through 4 except adjust Vbn and Vcn in turn.
