Testing secondary system supervision functions
7.6.1
Current circuit supervision CCSRDIF
Prepare the IED for verification of settings as outlined in section
settings.
Values of the logical signals for CCSRDIF are available on the local HMI under Main menu/
Tests/Function status/Secondary system supervision/CCSRDIF(87,INd)/CCSRDIF:X. The
Signal Monitoring in PCM600 shows the same signals that are available on the local HMI.
The Current circuit supervision function CCSRDIF is conveniently tested with the same three-
phase test set as used when testing the measuring functions in the IED.
The condition for this procedure is that the setting of
Ip>Block .
7.6.1.1
Verifying the settings
1.
Check the input circuits and the operate value of the
injecting current, one phase at a time.
2.
Check the phase current blocking function for all three phases by injecting current, one
phase at a time. The output signals shall reset with a delay of 1 second when the current
exceeds 1.5 ·
3.
Inject a current 0.1 ·
4.
Increase slowly the current in one of the phases current input and check that FAIL output
is obtained when the current is about 0.9 ·
7.6.1.2
Completing the test
Continue to test another function or end the testing by setting the parameter
under Main menu/Tests/IED test mode/TESTMODE:1. If another function is tested, then set
the parameter
system supervision/CCSRDIF(87,INd)/CCSRDIF:X for the function, or for each individual
function in a chain, to be tested next. Remember to set the parameter
individual function that has been tested.
7.6.2
Fuse failure supervision SDDRFUF
Prepare the IED for verification of settings as outlined in section
settings.
Values of the logical signals for SDDRFUF are available on the local HMI under Main menu/
Tests/Function status/Secondary system supervision/SDDRFUF/SDDRFUF:1. The Signal
Monitoring in PCM600 shows the same signals that are available on the local HMI.
The verification is divided in two main parts. The first part is common to all fuse failure
supervision options, and checks that binary inputs and outputs operate as expected according
to actual configuration. In the second part the relevant set operate values are measured.
