Commissioning Manual
During normal operating conditions, the BC input is de-energized.
2.
Apply a three-phase fault condition corresponding to a fault at approximately
45% of the line or with an impedance at 50% of used zone setting and current
greater than 30% of I
3.
Check that the correct trip outputs, external signals and indication are obtained.
Automatic initiation of ZCVPSOF
1.
Deactivate the switch onto fault BC input.
2.
Set current and voltage inputs to 0 for at least 1 second.
3.
Apply a three-phase fault condition corresponding to a fault at approximately
45% of the line or with an impedance at 50% of used zone setting and current
greater than 30% of I
4.
Check that the correct trip outputs, external signals and indication are obtained.
Completing the test
Continue to test another function or end the testing by setting the parameter TestMode
to Disabled 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/Impedance/ZCVPSOF/1:ZCVPSOF 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.

Values of the logical signals for PHPIOC (50) are available on the local HMI under
Main menu/Tests/Function status/Current/PHPIOC(50,I>>)/1:PHPIOC. The
Signal Monitoring in PCM600 shows the same signals that are available on the local HMI.
To verify the settings the following fault type should be tested:
