1. Activate the guard input signal (CRG) of the IED.
2. Using the scheme selected, check that a signal accelerated trip (TRIP) is obtained when the
guard signal is deactivated.

Completing the test

Continue to test another function or end the test by changing the TESTMODE setting to Off. Restore
connections and settings to the original values, if changed for testing purposes.
9.10.2 Current reversal and Weak-end infeed logic for distance
protection 3-phase ZCRWPSCH
Prepare the IED for verification of settings as outlined in section
section
Values of the logical signals for ZCRWPSCH are available on the local HMI under Main menu/Tests/
Function status / Scheme communication / ZCRWPSCH(85) /ZCRWPSCH:1.
The Signal Monitoring in PCM600 shows 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.

Current reversal logic

It is possible to check the delay of the CS send signal with tDelayRev by changing from a 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.
