1. Program the test equipment for a single-phase to earth fault and energize
FDPSPDIS and check that the input BLOCK on the power swing detection
function ZMRPSB is activated.
2. Make a test sequence so that a single-phase to earth fault occurs after that the
trajectory of the impedance has passed the outer and inner boundary of
ZMRPSB during power swing. Use the result from test of ZMRPSB above to
determine when the fault shall be applied. The earth-fault must be activated
before
tR1 has elapsed.
3. Start the sequence and observe that the START signal will not be activated.
6.4.1.4 Testing the block input, interaction between FDPSPDIS and ZMRPSB
Precondition
The BLOCK input is configured and connected to STPE output on the FDPSPDIS
function.
1. Make a test sequence so that a single phase-to-earth-fault occurs after that the
trajectory of the impedance has passed the outer boundary but not the inner
boundary of the power swing detection function ZMRPSB. Use the result from
test of ZMRPSBabove to instance when the fault shall be applied.
2. Start the test sequence by continuously reducing the voltage and observe that the
output signal ZOUT may come, but not START.
If the input I0CHECK is configured (connected to output signal STPE on
FDPSPDIS, the test of inhibit of ZMRPSB at earth-fault during power swing can
be done in the same way as for test of
tR1 .
6.4.1.5 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/TESTMODE:1 . If another function
is tested, then set the parameter Blocked to No under Main menu/Tests/Function test
modes/Impedance/ZMRPSB(68)/ZMRPSB:1 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.
6.4.2 Underimpedance protection for generators and transformers
ZGCPDIS
Values of the logical signals for ZGCPDIS are available on the local HMI under Main
menu/Tests/Function status/Impedance/ZGCPDIS(21G,Z<)/ZGCPDIS:1 . The
Signal Monitoring in PCM600 shows the same signals that are available on the local
HMI.
