7.3.1.3
Measuring the operating limit of set values with shaped load
encroachment characteristics
1.
Subject the IED to healthy normal load conditions for at least two seconds.
2.
Apply the fault condition and slowly decrease the measured impedance to find the
operating value of the phase-to-phase fault L1-L2 for zone 1 according to test point 1 in
figure
3.
Repeat steps
Observe that the zones that are not tested have to be blocked and the zone that is tested
has to be released.
4.
Repeat steps

7.3.1.4
Measuring the operate time of distance protection zones
1.
Subject the IED to healthy normal load conditions for at least two seconds.
2.
Apply the fault condition to find the operating time for the phase-to-phase fault
according to test point 7 in figure

7.3.1.5
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
ZQMPDIS(21,Z<)/ZQMPDIS:1 for the function, or for each individual function in a chain, to be
tested next. Remember to set the parameter
has been tested.
7.3.2
Phase selection with load encroachment, quadrilateral
characteristic FDPSPDIS
Prepare the IED for verification of settings as outlined in section
settings.
Values of the logical signals for FDPSPDIS are available on the local HMI under Main menu/
Tests/Function status/Impedance/FDPSPDIS/FDPSPDIS:1. The Signal Monitoring in PCM600
shows the same signals that are available on the local HMI.

Test point 6 is intended to test the directional line of impedance
protection. Since directionality is a common function for all 5 measuring
zones, it is only necessary to test point 6 once, in the forward direction.
Directional functionality testing (trip inside, no-trip outside) should
always be carried for all impedance zones set with directionality (forward
or reverse).
