11.4.7.4 Measuring the operating time of distance protection zones
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 for zone 1. Compare the result of the measurement to the setting tPPZ1.
3. Repeat steps
12. Compare the result of the measurement to the setting t1PG.
4. Repeat steps
The zones that are not tested have to be blocked and the zone that is tested has to be released.
11.4.7.5 Completing the test
Continue to test another function or end the test by changing the TESTMODE setting to Disabled.
Restore connections and settings to the original values, if changed for testing purposes.

11.4.8.2 Verifying the 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.

2.2.4 Zone BU (Backup) is added. Now there are seven zones in total. Zone 2 direction and
directional blinders (ArgDir, ArgNegRes) are now settable. Setting tTauDC is added; a
parameter for optional fine tuning of performance.
Added new setting RStart, which limits the resistive reach of the phase selection outside of
the ArgLd sector. Changed setting name XLd to XStart.
2.2.5 Parallel line mutual coupling compensation feature based on the parallel line residual current
is added with new settings: EnaPar, INPRatio, R0MZ1, X0MZ1, R0MZ2, and X0MZ2.
Load compensation and direction element are improved for earth faults without zero
sequence current condition.
This update is valid for all the previously released 2.2 products.
