During normal operating conditions, the
BC
input is de-energized.
3.
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.
4.
Check that the
TRIP
output, external signals and indication are obtained. The
TRIP
output will be obtained
tSOTF
after the
BC
input is activated.
10.4.1.2
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
tDuration
.
4.
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 after 15 ms from the
ZACC
input activation.
10.4.1.3
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
tDuration
.
4.
Apply the two-phase currents in such a way that the magnitudes are greater
than
IPh<
and the two-phase voltages in such a way that the magnitudes are
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.
The timing of the
TRIP
output depends on the
tDuration
setting and the
distance protection release of the
ZACC
input signal.
•
If
ZACC
comes before the elapse of
tDuration
,
TRIP
will be activated
tDuration
+15 ms after
UPh
and
IPh
changes are done.
•
If
tDuration
elapses before the
ZACC
input signal activates,
TRIP
will
be activated 15 ms after the
ZACC
activation.
10.4.1.4
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.
