13.4.2.2 Measuring the operating time of distance protection zones
GUID-BB93C603-F43E-40CB-8EFA-3B0F280C011D v5
Procedure:
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 12 in figure
42 and table 19 for zone 1. Compare the result
of the measurement to the setting tPPZ1.
3. Repeat steps 1 to 2 to find the operating time for the phase-to-ground fault
according to test point 12 in figure 43 and table 20. Compare the result of the
measurement to the setting t1PG.
4. Repeat steps
1 to 2 to find the operating time for all other used measuring zones.
The zones that are not tested have to be blocked and the zone that is tested has to
be released.

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

Prepare the IED for verification of settings outlined in Section
"Preparing the IED to
verify settings".
Measure operating characteristics during constant current conditions. Keep the
measured current as close as possible to its rated value or lower. But make sure it is
higher than the set minimum operating current.
Ensure that the maximum continuous current to the IED does not exceed four times its
rated value, if the measurement of the operating characteristics runs under constant
voltage conditions.
The test procedure has to take into consideration that the shaped load encroachment
characteristic is active. It is therefore necessary to check the setting. To verify the
settings with the shaped load encroachment characteristic the test should be carried out
according to figures
44 and 45 and tables 21 and 22. In cases where the load
