5.2.2 T2 – IT TRIP SUPERVISION TEST
1.
Settings:
Z1DISTANCE
(104)
Z1GROUND = YES
CURSUPVIS
(501)
IT_PICKUP = 0.25 (0.05) amps
2.
Connect the relay as shown in Figure 4–3: PHASE TO GROUND TEST CONNECTIONS on page 4–14.
3.
Set the relay into test mode 34 (IT Detector). The LUI should display
IT DETECTOR ON
4.
Set the voltages as follows:
VA = 67 V rms
∠
0°
VB = 67 V rms
∠
–120°
VC = 67 V rms
∠
+120°.
5.
Set
I
op
to 0.40 (0.08) A rms and apply to the relay. The A1 contact should close. Lower
I
op
to 0.15 (0.03) A
rms, at which point the A1 contact should open.
6.
Reduce
I
op
to 0.

VC = 67 V rms
∠
+120°
5.
Set
I
op
to 0.30 (0.06) A rms and apply to the relay. The A1 contact should close. Lower
I
op
to 0.10 (0.02) A
rms, at which point the A1 contact should open.
6.
