WD2759 Over/Undervoltage Relays
Function 27/59
ANSI/IEEE C37.90-1978
WD2759 Operation
WD2759 AC voltage sensing relays provide voltage monitoring and protection
in AC systems from 50 to 400 Hz. Sensing voltages, number of phases, over
and undervoltage setpoint, and time delays are user congured. WD2759
voltage relays operate when the externally adjustable trip point is reached.
An external time delay control is provided with an adjustment of .5 to 10 sec-
onds. This time delay may be used to prevent false tripping when there are
slight variations in the voltage supply. On overvoltage (OV) the output relay
energizes when the input signal exceeds the trip point. On undervoltage (UV)
the output relay energizes when the input signal goes below the trip point. A
green LED indicates power to the relay. Red LED lights indicate the state of
the undervoltage and overvoltage trips.
WD2759 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
voltmeter in parallel with the input signal. Use the following procedure to
calibrate your relay.
OVER VOLTAGE
1. Remove cover.
2. Adjust the TRIP SET control fully clockwise (CW) and the TIME DELAY
control fully counterclockwise (CCW).
3. Apply the desired trip voltage to the relay.
4. Slowly adjust the TRIP SET control CCW until the relay trips.
5. Remove the applied voltage (do not change the voltage level) and set
the TIME DELAY control to the desired time delay.
6. Apply the trip voltage 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.
UNDER VOLTAGE
1. Remove cover.
2. Adjust the TRIP SET control fully CCW and the TIME DELAY control fully
CCW.
3. Decrease the applied sensing voltage from the nominal value until the
desired tripping voltage is reached.
4. Slowly adjust the TRIP SET control CW until the relay trips.
5. Set the TIME DELAY control to the desired time delay and apply nomi-
nal voltage to the relay.
6. Step down the applied voltage from nominal to a level jest below the trip
level set in Step 3 and measure the time delay.
7. Adjust the TIME DELAY and repeat steps 4 and 5 until the desired time
delay is achieved.
