4.
Set the voltage inputs to the following values:
VA: 67 volts rms
∠
0°,
VB: 67 volts rms
∠
–120°,
VC: 67 volts rms
∠
+120°.
5.
Set the fault current,
I
op
, phase angle to
∠
I
3
= [________]° lagging. Note that the leading phase angle is
180° out of phase with the line to which it is shorted.
6.
Set the fault current to
I
T
= [________] A rms. Simultaneously reduce the voltages of the faulted phases
and check that the A1 contact closes when the voltages are within 7% of
V
NOM
3
.
7.
Reduce the fault current to zero. Note that the trip target indication concurs with the fault. For example, an
AB fault is displayed as:
TRIP: AB Z3 "DIST"
where “DIST” is the displayed target.
8.
Repeat the test for phase BC and CA faults.
