made for all impedance zones set with directionality (forward orreverse).13.4.2.2 Measuring the operating time of distance protection zonesGUID-BB93C603-F43E-40CB-8EFA-3B0F280C011D v5Procedure: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 faultaccording to test point 12 in figure 42 and table 19 for zone 1. Compare the resultof the measurement to the setting tPPZ1.3. Repeat steps 1 to 2 to find the operating time for the phase-to-ground faultaccording to test point 12 in figure 43 and table 20. Compare the result of themeasurement 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 tobe released.13.4.2.3 Completing the test GUID-60C5389E-B021-45BB-8CB3-E21348CF50EF v2Continue to test another function or end the test by changing the TESTMODE setting toDisabled. Restore connections and settings to their original values, if they werechanged for testing purposes.13.4.3 High Speed distance for series compensated line zones,quadrilateral and mho characteristic ZMFCPDIS (21)GUID-EE954483-7157-4EA2-A5DD-537DF6864BC2 v4Prepare the IED for verification of settings outlined in Section "Preparing the IED toverify settings".Measure operating characteristics during constant current conditions. Keep themeasured current as close as possible to its rated value or lower. But make sure it ishigher than the set minimum operating current.Ensure that the maximum continuous current to the IED does not exceed four times itsrated value, if the measurement of the operating characteristics runs under constantvoltage conditions.The test procedure has to take into consideration that the shaped load encroachmentcharacteristic is active. It is therefore necessary to check the setting. To verify thesettings with the shaped load encroachment characteristic the test should be carried outaccording to figures 44 and 45 and tables 21 and 22.
