Checking of current reversal
M14947-13 v9
The reverse zone timer must not operate before the forward zone
fault is applied. The user might need to block the reverse zone timer
setting during testing of current reversal.
The forward zone timer must be set longer than the tDelayRev set
value.
1. Set the healthy condition to an impedance at 50% of the reach of the reverse
zone connected to IRV.
2. Activate the receive (CRL) signal.
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
tDelayRev setting
longer than the carrier accelerated trip (TRIP) recorded for the permissive
overreach scheme communication.
5. Restore the forward and reverse zone timer to its original setting.

Weak-end infeed logic at permissive overreach schemes
M14947-39 v5
1. Check the blocking of the echo with the injection of a CRL signal >40ms
after a reverse fault is applied.
2. Measure the duration of the echoed CS signal by applying a CRL receive
signal.
3. Check the trip functions and the voltage level for trip by reducing a phase
voltage and applying a CRL receive signal.
Testing conditions
M14947-52 v7
Only one type of fault is sufficient, with the current reversal and weak-end infeed
logic for distance protection function ZCRWPSCH. Apply three faults (one in each
phase). For phase L1-N fault, set these parameters:
