WD32 Reverse Power Relays
Function 32
WD32 Operation
WD32 reverse power relays are used to monitor the direction of power from
AC generators. This is accomplished by measuring I cos q. If current from
the generator is reversed and exceeds the adjustable setting, the relay will
trip. A 0.5 to 20 second time delay is provided. A correct setting of the trip
point and time delay will prevent motorizing the generator and prevent tripping
during transients that occur while synchronizing. A POWER LED indicates the
condition of the power supply and a REVERSE POWER TRIP LED indicates
the output status of the relay.
WD32 Calibration
The calibration marks on the faceplate have a maximum error of 10% and
are provided only as guides. Proper calibration requires using an accurate
Current Meter in series with the input current. Use the following procedure
to calibrate your relay.
REVERSE POWER
1.
Remove cover.
2.
Adjust the TRIP SET control fully clockwise (CW) and the TIME DE-
LAY control fully counterclockwise (CCW).
3.
Apply the desired trip current to the relay. NOTE: for the Reverse
Power (WD32-00X) a resistive load must be used and for the Reverse
KVAR (WD32-01X) an inductive load must be used.
4.
Slowly adjust the TRIP SET control CCW until the relay trips.
5.
Remove the applied Current and set the TIME DELAY control to the
desired time delay.
6.
Re-apply the Current (10% more than the trip current) to the relay and
measure the time to trip.
7.
Adjust the TIME DELAY and repeat steps 4 and 5 until you have the
desired time delay.
