Completing the test

Continue to test another function or end the testing by setting the parameter
under Main menu/Tests/IED test mode/TESTMODE:1. If another function is tested, then set
the parameter
communication/ZCRWPSCH(85)/ZCRWPSCH:1 for the function, or for each individual function
in a chain, to be tested next. Remember to set the parameter
individual function that has been tested.
7.9.3 Current reversal and WEI logic for distance protection, phase
segregated ZCWSPSCH
Prepare the IED for verification of settings as outlined in section
settings.
Values of the logical signals for ZCWSPSCH are available on the local HMI under Main menu/
Tests/Function status/Scheme communication/ZCWSPSCH(85)/ZCWSPSCH:1. The Signal
Monitoring in PCM600 shows the same signals that are available on the local HMI.
The current reversal logic and the weak-end infeed functions are tested during the secondary
injection test of the impedance or overcurrent protection zones together with the Scheme
communication logic for the distance protection function ZCPSCH .
7.9.3.1

Current reversal logic

It is possible to check the delay of the CS send signal with
reverse to a forward fault.
By continuously activating the CR input and changing from a reverse to a forward fault, the
delay tDelayRev can be checked.
Checking of current reversal
The reverse zone timer must not operate before the forward zone fault is applied. The user
might need to increase the reverse zone timer setting during testing of current reversal.
1. Activate the receive (CRL) signal.
2. Set the healthy condition to an impedance at 50% of the reach of the reverse zone
connected to IRVL.
3. After the start condition is obtained for reverse zone, apply a fault at 50% of the reach of
the forward zone connected to WEIBLK2.
4. Check that correct trip outputs and external signals are obtained for the type of fault
generated.
The operation time should be about the
accelerated trip (TRIP) previously recorded for permissive scheme communication.
5. Restore the forward and reverse zone timer to its original setting.
