9.3.4.1
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.
9.3.4.2
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.
9.3.4.3
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.
9.3.4.4
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.
