Basler BE3-GPR - Overfrequency Trip (Line-To-Line Frequency Sensing); Neutral Ground Fault Trip (5 A NGF CT Current Sensing); Overcurrent Trip (5 A A, B, or C CT Current Sensing); Reactive Current Trip (5 A CT B Current Sensing)

Testing 7-3
Step 4. Increase phase B, line-to-neutral voltage from 69.3 V
RMS
to 100 V
RMS
. The relay should be
flashing the overvoltage tripped condition on the front panel LCD. Return the voltage to 69.3
V
RMS
and the LCD should return to the un-tripped ON display.
Step 5. Increase phase C, line-to-neutral voltage from 69.3 V
RMS
to 100 V
RMS
. The relay should be
flashing the overvoltage tripped condition on the front panel LCD. Return the voltage to 69.3
V
RMS
and the LCD should return to the un-tripped ON display.
Overfrequency Trip (Line-To-Line Frequency Sensing)
Step 1. Monitor the OVR FREQ output contacts, terminals 43 and 44, for the trip condition.
Step 2. Increase 3-phase voltage frequency from 60 Hz to 62 Hz. The relay should be flashing the
overfrequency tripped condition on the front panel LCD. Return the frequency to 60 Hz and the
LCD should return to the un-tripped ON display.
Neutral Ground Fault Trip (5A NGF CT Current Sensing)
Step 1. Use the front panel keypad to change from 3-phase line-to-line sensing to single phase line-to-
line sensing.
Step 2. Monitor the NG FAULT output contacts, terminals 52 and 53, for the trip condition.
Step 3. Increase AC current from 0 to 0.3 Amps. The relay should be flashing the neutral ground fault
tripped condition on the front panel LCD. Return the current to 0 Amps and the LCD should
return to the un-tripped ON display.
Overcurrent Trip (5A A, B, or C CT Current Sensing)
Step 1. Use the front panel keypad to change from 3-phase line-to-line sensing to single phase line-to-
line sensing.
Step 2. Monitor the OVR CUR output contacts, terminals 52 and 53, for the trip condition.
Step 3. Increase AC current from 0 to 2.0 Amps on any phase. After a 1 second delay the relay should
be flashing the overcurrent tripped condition on the front panel LCD. Return the current to 0
Amps and the LCD should return to the un-tripped ON display.
Reactive Current Trip (5A CT B Current Sensing)
Step 1. Connect the AC Current source to the 5A CT B input (terminal 31) and the CT COM input
(terminal 35).
Step 2. Monitor the REACT CUR output contacts, terminals 64 and 65, for the trip condition.
Step 3. Use the front panel keypad to scroll though the LCD based setup menu and enable the
Reactive Current Trip function, but leave the trip, reset and time delay values at their default
levels.
Step 4. Set AC current phase angle to 90
°
relative to phase B-to-Neutral voltage. Increase AC current
from 0 to 0.2 Amps. The relay should be flashing the reactive current tripped condition on the
front panel LCD. Return the current level to 0 Amps and the LCD should return to the un-
tripped ON display.
Reverse Power Trip (5A CT B Current Sensing)
Step 1. Monitor the REV PWR output contacts, terminals 61 and 62, for the trip condition.
Step 2. Use the front panel keypad to scroll though the LCD based setup menu and enable the
Reverse Power Trip function, but leave the trip, reset and time delay values at their default
levels.
