Testing secondary system supervision functions

Current circuit supervision CCSRDIF

Prepare the IED for verification of settings as outlined in
verify settings".
Values of the logical signals are available on the local HMI under: Main menu/
Tests/Function status/<Function group>/<Function>/<1:Function>. The Signal
monitoring tool in PCM600 shows the same signals that are available on the LHMI.
Current circuit supervision (CCSRDIF) is conveniently tested with the same 3-
phase test set as used when testing the measuring functions in the IED.
The condition for this procedure is that the setting of IMinOp is lower than the
setting of Ip>Block

Verifying the settings

Procedure:
1. Check the input circuits and the operate value of the IMinOp current level
detector by injecting current, one phase at a time
2. Check the phase current blocking function for all three phases by injection
current, one phase at a time. The output signals shall reset with a delay of 1
second when the current exceeds 1.5*IBase
3. Inject a current 0.9*IBase to phase L1 and a current 0.15*IBase to the
reference current input IREFSMPL
4. Decrease slowly the current to the reference current input and check that
blocking is obtained when the current is about 0.1*IBase

Completing the test

Continue to test another function or end the testing by setting the parameter
TestMode to Off under Main menu/Tests/IED test mode/1:TESTMODE. If
another function is tested, then set the parameter Blocked to No, under Main menu/
Tests/Function test modes/<Function group>/<Function>/<1:Function> for the
function, or for each individual function in a chain, to be tested next. Remember to
set the parameter Blocked to Yes, for each individual function that has been tested.
