Installation and Maintenance

Information

Installation — To mount the WD

series protective relay on a DIN rail,

hook the top edge of the cutout on the

base of the case over one edge of the

DIN rail, then press the opposite side of

the cutout containing the release clip

over the opposite side of the DIN rail. To

remove or reposition the relay, lever the

release clip and move the relay as

required. WD series relays should be

installed in a dry location where the

ambient temperature will be within the

operating temperature range.

Maintenance — WD series protective

relays are solid state devices that require

no maintenance. They are not designed

to be serviced by the user. Consult

KILOVAC customer service at 805-220-

2023 if repairs should be necessary.

Users should thoroughly review the

technical data before selecting a product

part number. It is recommended that user

also seek out the pertinent approvals

files of the agencies/laboratories and

review them to ensure the product meets

the requirements for a given application.

Outline Dimensions

The WD series offers

several different models

of protective relays in a

common package that is

suitable for either DIN rail

or screw mounting. These

WD25 Operation

WD25 paralleling relays

are used to ensure that two

circuits are synchronized.

When voltage, phase

relationship and frequency

are within the selected

synchronizing limits, the

output relay will energize.

The WD25 paralleling relay

allows for a generator to be

brought online without dam-

age or system disturbance.

WD25 series with a "dead

bus" feature will energize for

a synchronized condition or

an "on line" generator, "dead

bus" condition. This "dead

bus" feature allows the gen-

erator to energize a dead

bus. The "double dead bus"

feature permits paralleling

of two buses when: (a) both

the line voltages are equal

and in phase, or (b) when

either bus is "hot" and the

other bus is "dead."

WD25 Specifications

120, 208, 277 or 480 VAC, selectable.

Maximum Sensing Range —

575VAC.

Nominal Frequency Range —

40-400 Hz.

Contact Form — 2 form C (DPDT).

WD25 Calibration

The calibration marks on the faceplate

are provided only as guides. Proper

calibration requires using an accurate

voltmeter. Use the following procedure

to calibrate the WD25:

1. Remove the cover.

2. Adjust the SYNC VOLTAGE control

fully counterclockwise (CCW). Apply

nominal voltage to the LINE B (bus)

sensing terminals.

3. Apply the maximum desired

synchronization voltage to the LINE A

(generator) terminals. This voltage

should be in phase with LINE B (bus)

voltage and have the same frequency.

4. Slowly adjust the SYNC VOLTAGE

control clockwise (CW) until the relay

energizes.

WD2759 Operation

WD2759 AC voltage sens-

ing 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 config-

ured. WD2759 voltage

relays operate when the

externally adjustable trip

point is reached. An exter-

nal time delay control is

provided with an adjustment

of .5 to 10 seconds. 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 ener-

gizes 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.

WD32 Operation

WD32 reverse power relays

are used to monitor the

direction of power from AC

generators. This is accom-

plished by measuring I cos

q. If current from the gener-

ator is reversed and

exceeds the adjustable set-

ting, 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 motoriz-

ing the generator and pre-

vent 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.

WD47 Operation

WD47 phase sequence

relays are designed to

monitor the correct phase

rotation and loss of phase

of three phase ac systems

from 50 to 400 Hz. An

incorrect phase sequence

or loss of any phase will

cause the WD47 to pickup.

When the phase sequence

is corrected or the lost

phase is restored the

contacts dropout. Red

LED's light to indicate a

fault condition. A green

LED indicates power to the

relay. The WD47 is often

used to detect reverse

phase rotation or loss of

phase to generators, busses,

motors, and transformers.

WD47 Specifications

Nominal Operating Range —

120 to 480 VAC.

Maximum Sensing Range —

575VAC.

Nominal Frequency Range —

40-400 Hz.

Contact Form — 2 form C (DPDT).

WD47 Calibration

The WD47 has no adjustments and

no calibration is necessary. Proper

operation may be verified as follows:

1. Apply a nominal, three-phase input

with the correct phase sequence.

The output relay should dropout and

the green LED should light.

2. Apply a nominal, three-phase input

with an incorrect phase sequence.

The output relay should pickup and

the red LED should light.

3. Apply only one or two phases with

the correct phase sequence. The

output relay should pickup and the

red LED should light.

WD5051 Operation

WD5051 AC current sens-

ing relays provide current

monitoring and protection in

AC systems from 50 to 400

Hz. Nominal Sensing

Current, Instantaneous Over

Current setpoint, Time Over

Current setpoint, and Time

Over Current time delay are

user configured. WD5051

current relays operate when

the externally adjustable trip

point is reached. An exter-

nal time over current time

delay control is provided

with an adjustment of .5 to

20 seconds. This time delay

may be used to prevent

false tripping when there

are slight variations in the

sensed current. With control

power applied, the

Instantaneous Over Current

(IOC) contacts pick-up

when the input signal

exceeds the IOC trip set-

point. Similarly, with control

power applied, the Time

Over Current (TOC) con-

tacts pick-up after the pre-

set time delay when the

Sense Current rises above

the TOC trip setpoint. The

IOC contacts may also be

configured to function as an

under current relay. A

green LED indicates power

to the relay. Red LED lights

indicate the state of the IOC

and TOC trips.

WD5051 Calibration

The calibration marks on the faceplate

are provided only as guides. Proper cal-

ibration requires using an accurate

ammeter in series with the current

source. Use the following procedure to

calibrate your relay:

OVERCURRENT

1. Remover the cover.

2. Adjust the TRIP SET control fully

clockwise (CW) and the TIME DELAY

control (TOC only) fully counter-

clockwise (CCW).

3. Apply the desired trip current to the

relay.

4. Slowly adjust the TRIP SET control

CCW until the relay trips.

5. Remove the applied current (do not

change the current level). Set the

TIME DELAY (TOC only) control to

the desired time delay.

Close Differential Relays are

voltage sensitive. The pick-

up and drop-out voltage

settings are independently

adjustable, which allows

precise setting of the differ-

ential voltage. This relay is

available in a wide range of

AC and DC voltages. Their

primary application is the

sensing and control of

transfer switches.

Operation

Monitors a single phase

AC signal, and is used for

undervoltage detection.

Has separate pick-up and

drop-out voltage settings,

providing an adjustable

hysteresis.

Expected Life — 10 million opera-

tions

Inverse Time Drop-Out —

The differential relay contains a time

delay before operation so that momen-

tary voltage transients do not affect the

operation of the relay. The time delay

has an inverse time characteristic so that

excessive voltage conditions will cause a

more rapid drop-out. This time delay is

approximately 200mSec. (12 cycles) at

the trip settings and decreases to 30

mSec. at approximately 15% beyond the

trip settings.

Notes:

1. Remove black nylon protective

screws to gain access to the two

internal adjustment potentiome-

ters.

2. Clockwise rotation of the pick-up

and drop-out adjustment will raise

the voltage trip point.

3. The relay contacts are shown in

the de-energized state.

Current Differential Relays

are used for the protection

of transformers, motors and

generators, by comparing

the magnitude of the current

entering and leaving the

protected circuit. On a

given phase winding, any

difference between the two

currents will indicate an

internal fault; the relay will

sense the vectorial differ-

ence between the two cur-

rents of the protected

section and will initiate a

quick disconnection of the

unit, to prevent disastrous

consequences.

The relay may also be used

to protect internal faults on

transformers, such as:

ground faults, shorted wind-

ing, leakage between pri-

mary and secondary, etc. It

will sense and compare pri-

mary vs. secondary cur-

rents, once the turns ratio

has been taken into consid-

eration.

Operation

With control voltage

applied, the output contacts

(shown in the de-energized

position) will remain de-

energized as long as the

difference between the two

input currents remains

below the preset trip value.

The contact will transfer to

Application

These relays are designed

for automatic paralleling

(synchronizing) of genera-

tors. The relays sense the

phase angle displacement

and the amplitude differ-

ence between two voltages

and permit paralleling only

when both voltages are

equal and in phase. A short

time delay is provided to

assure that the frequencies

are essentially the same at

the moment of paralleling.

The basic series is designed

to parallel two or more

energized AC generators.

The “Dead Bus” type

provides paralleling of AC

generators to the main bus.

They permit electrical con-

nection of an energized gen-

erator to an un-energized

line (Dead Bus). If the bus

is energized, connection of

the generator to the bus is

permitted only when both

are synchronized.

Product Specifications

Sensing Voltage — 120 V, 230 V,

277 V, 380 V, 460 V, 575 V, & 415 V

Line Frequency — 50-500 Hz

Pick-Up Adjustment —

External adjustment for field sensing

of 10-30% of nominal input voltage.

(Vertical voltage differential of 6 to 18

electrical degrees).

Time Delay — Fixed @ 60 millisec-

onds is provided to assure that the fre-

quencies of both input lines are

sufficiently close to permit paralleling

within the preset window.

Ground Fault Detectors

are used to sense leakage

current to ground in power

transformers and genera-

tors. They are available for

both AC and DC systems.

Some generator systems

provide auxiliary power

outlets for small equipment.

TE Connectivity GFD’s

eliminate personnel risk of

accessing these outlets if a

ground fault exists. Diesel

locomotives and railroad

line signal boxes also use

GFD’s for operational con-

trol purposes. The GFD

monitors both positive and

negative grounds for fault

currents and can trigger

either notification or system

shutdown if these are

detected. GFD’s are avail-

able for both grounded and

ungrounded systems.

Ground Fault Detectors are

designed to provide very

sensitive Ground-Current

protection for motor, equip-

ment and personnel from

damage or electrical shock.

In a ground system, the

leakage current is moni-

tored through a toroidal or

doughnut current trans-

former placed around the

supply conductors to a

motor, transformer, equip-

ment or outlets. Since the

sums of the current in a sys-

tem add to zero, the relay is

responsive only to ground-

fault current.

Operation

The output contacts are

shown in de-energized

position. They will change

state when these conditions

are met:

1. Control voltage is

applied.

2. Leakage current exceed

the trip setting.
