1.
Program the test equipment for a single-phase to ground fault and energize
FDPSPDIS (21) and check that the input BLOCK on the power swing detection
function ZMRPSB (68) is activated.
2.
Make a test sequence so that a single-phase to ground fault occurs after that the
trajectory of the impedance has passed the outer and inner boundary of ZMRPSB
(68) during power swing. Use the result from test of ZMRPSB (68) above to
determine when the fault shall be applied. The ground-fault must be activated
before
tR1
has elapsed.
3.
Start the sequence and observe that the PICKUP signal will not be activated.
6.3.5.4
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/ZMRPSB(68)/1:ZMRPSB
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.
6.3.6
Automatic switch onto fault logic, voltage and current based
ZCVPSOF
Prepare the IED for verification of settings as outlined in
Values of the logical signals for ZCVPSOF are available on the local HMI under
Main
menu/Tests/Function status/Impedance/ZCVPSOF/1:ZCVPSOF
. The Signal
Monitoring in PCM600 shows the same signals that are available on the local HMI.
Automatic switch onto fault logic, voltage and current based function ZCVPSOF is
checked using secondary injection tests together with the Scheme communication logic
for distance or overcurrent protection function ZCPSCH (85) and with the dead line
detection function (DLD), which is embedded in ZCVPSOF. ZCVPSOF is activated
either by the external input BC, or by the internal DLD. SDDRFUF is done with a pre-
fault condition where the phase voltages and currents are at zero. A reverse three-phase
fault with zero impedance and a three-phase fault with an impedance corresponding to
the whole line is applied. This fault shall cause an instantaneous trip and result in a
TRIP indication.
6.3.6.1
External activation of ZCVPSOF
1.
Activate the switch onto fault BC input.
