11.4.13.1 Activating ZCVPSOF externally
M13850-14 v8
1. Set AutoInitMode to DLD disabled and Mode to Impedance .
2. Activate the switch onto fault
BC
input.
During normal operating conditions, the
BC
input is de-energized.
3. Apply a three-phase fault condition corresponding to a fault at approximately
45% of the line or with impedance at 50% of the used zone setting and
current greater than 30% of
IBase .
The
ZACC
input is activated.
4. Check that the
TRIP
output, external signals and indication are obtained.
11.4.13.2 Initiating ZCVPSOF automatically and setting mode to impedance
M13850-27 v8
1. Set AutoInitMode to Voltage and Mode to Impedance .
2. Deactivate the switch onto fault
BC
input.
3. Set the current and voltage inputs to lower than IPh< and UPh< for at least
one second.
4. Apply a three-phase fault condition corresponding to a fault at approximately
45% of the line or with impedance at 50% of the used zone setting and
current greater than 30% of
IBase .Apply a two-phase fault condition
corresponding to a fault at approximately 45% of the line or with impedance
at 50% of the used zone setting and current greater than 30% of
IBase .
The
ZACC
input is activated.
5. Check that the correct
TRIP
output, external signals and indication are
obtained.
11.4.13.3 Initiating ZCVPSOF automatically and setting mode to UILevel
GUID-E83E1B3D-026C-48DB-BB9B-43C6597DE5DB v5
1. Set AutoInitMode to Voltage and Mode to UILevel .
2. Deactivate the switch onto fault
BC
input.
3. Set the current and voltage inputs to lower than IPh< and UPh< for at least
one second.
4. Apply the three-phase currents in such a way that the magnitudes are greater
than
IPh< and the three-phase voltages in such a way that the magnitudes and
lower than UPh< at least for the duration of the tDuration setting.
5. Check that the correct
TRIP
output, external signals and indication are
obtained.
11.4.13.4 Completing the test
M13850-41 v5
Continue to test another function or end the test by changing the TESTMODE
setting to Off . Restore connections and settings to their original values, if they were
changed for testing purposes.
