Step 24: Apply a 120 Vac, three-phase voltage source at nominal frequency to terminals C13 (A-phase),
C14 (B-phase), C15 (C-phase), and C16 (Neutral). Reduce the A-phase voltage to 40 Vac.
View the Metering screen on the front-panel display to verify that the zero sequence voltage is
greater than 80 volts.
Step 25: Set A-phase current source to 0 amps with an angle of 80 degrees lagging (zero sequence line
angle) and slowly increase the current until OUT2 closes. Decrease A-phase current until OUT2
just drops out. Pickup will occur within
±
2% of the 50-2 pickup setting (1.96 A to 2.04 A).
Dropout will occur at approximately 95% of the actual pickup value. Verify that there is a 50-2-
67-Residual target on the front-panel display.
Step 26: With the same voltage still applied, increase the A-phase current until OUT2 closes. Swing the
angle of the applied c90 degrees and –90 degrees away from the 80-degree zero-
sequence line angle. Verify that OUT2 opens at approximately 170 degrees lagging and 350
degrees lagging. OUT2 should remain closed from 170 through 80 to 350 degrees lagging
(defined as forward trip direction). Steps 23 through 26 verify polarizing reference quantities
V0IN, with 50-2 set to operate for calculated 3I0 as per Table 217. The 50-2 element can also
be set to operate for measured ground current IG while still being polarized by V0IN. To verify,
connect A-phase current in series with IG current. That is, polarity current should go in D1 out
D2, in D7 out D8. Repeat steps 24 through 26 with 50-2 mode set for IG operate and 50-2
target set for 50-2-67-IND GND. Verify that there is a 50-2-67-IND GND target on the front-
panel display.
Step 27: Set Zero Sequence Mode to VOIG on the Protection, Current, Directional (67-1) screen. The
polarizing reference quantities are V0 compared to IG measured. This compares calculated V0
to measured IG (independent ground input). Repeat steps 24 through 26 with A-phase current
connected in series with IG current. That is, polarity current should go in D1 out D2, in D7 out
D8.Verify that there is a 50-2-67-IND GND target on the front-panel display. Note that 50-2 can
also be set to operate for calculated IN (3I0) while still being polarized by V0IG. Verify operation
by repeating steps 24 through 26 with 50-2 set for 3I0 operate. Verify that there is a 50-2-67-
Residual target on the front-panel display.
Step 28: Set Zero Sequence Mode to VXIG on the Protection, Current, Directional (67-1) screen. Set 50-
2 mode to IG on the Protection, Current, Instantaneous Overcurrent (50-2) screen. The
polarizing reference quantities are an external source of 3V0 applied at the VX input compared
to measured IG (independent ground input). Apply polarity of a single-phase voltage source (30
Vac at nominal frequency) to terminal C17 and non-polarity to C18 at an angle of 180 degrees
lagging. An angle of 180 degrees is used to simulate a broken delta voltage where polarity to
non-polarity is 180 degrees out of phase with, for example, the A-phase current during an A-
phase to ground fault. The BE1-11
g
internally compensates for the 180 degree phase difference
such that polarity voltage from the broken delta source connected to polarity of the BE1-11
g
results in a 0 degree condition for a Forward fault. To verify, connect A-phase current in series
with IG current. That is, polarity current should go in D1 out D2, in D7 out D8. Repeat steps 25
and 26 with 50-2 set for IG operate. Verify that there is a 50-2-67-IND GND target on the front-
