Completing the test
Continue to test another function or end the test by changing the Test mode setting to Off. Restore
connections and settings to their original values, if they were changed for testing purposes.
10.4.4
Catenary distance protection ZRCPDIS
Prepare the IED for verification of settings outlined in Section
Values of the logical signals for ZRCPDIS are available on the local HMI under Main menu /Test/
Function status /Impedance protection/DistanceProt1Ph(21,Z<) /ZRCPDIS(21;Z<):x , where x =
1 or 2.
The Signal Monitoring tool in PCM600 shows the same signals that are available on the local HMI.

Verifying the signals and settings
Measure the operating characteristics during constant current conditions. Keep the measured current
as close as possible to the rated value of the IED or lower. Ensure that it is higher than the set
minimum operating current.
Ensure that the maximum continuous current to the IED does not exceed four times of its rated
value, if the measurement of the operating characteristics runs under constant voltage conditions.
To verify the settings, test the operating points given in the following figure by injecting appropriate
voltage and current(s) to the IED through a secondary injection kit.
Always set Operation to On to check the performance of distance protection during testing.
Ensure that the setting parameter TESTMODE is set to ON.
Testing the measuring zone
1.
Set OpZx to On, DirModeZx to Forward, and LEModeZx to On.
Where, x indicates the measuring zone under testing.
2.
Set ArgNegRes and ArgDir settings.
3.
Set XFWZx, XRVZx, CharAng, ArgLd, RFFwZx and RFRvZx settings accordingly. Also, ensure
that RLd value is lower than the RFFwZx set value.
The test points that are to be considered for measurement accuracy of set reactance reach are
shown in Figure

2.2.2
Added ZRCPDIS function
2.2.3
Seal-in voltage level is increased to 10.0% UB and internal time delay of one
fundamental power cycle for seal-in detection is added for stable direction detection and
trip indication even with low voltage conditions during fault. Operating time improvement
for faults occurrence around 90.0% to 95% of set reach for all measuring zones. No
maloperation from instantaneous measuring zones at CB opening.
