Section 10
Testing functionality by secondary injection
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
IEC17000094 V1 EN-US
