Section 11
Testing functionality by secondary injection
1. Connect the test set for injection three-phase voltages to the appropriate voltage
terminals of the IED.
2. Inject voltage(s) in a way that relevant measured (according to setting parameter
VoltageInput ) voltages are created from the test set.
3. Overall check in principal as above (non-directional overcurrent feature) and
correspondingly for the undervoltage feature.

Completing the test

continue to test another function or end the test by changing the
Restore connections and settings to their original values, if they were changed for testing
purposes.

Secondary system supervision

11.9.1

Current circuit supervision CCSSPVC

Prepare the IED for verification of settings outlined in Section
settings".
The Current circuit supervision function CCSSPVC 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 .
11.9.1.1

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 and check that FAIL output is obtained
when the current is above 0.9 ·
11.9.1.2 Completing the test
continue to test another function or end the test by changing the
Restore connections and settings to their original values, if they were changed for testing
purposes.
11.9.2

Fuse failure supervision FUFSPVC

Prepare the IED for verification of settings as outlined in section
section
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.
