Paralleling Relays

Function:

• ANSI/IEEE C37.90-1978

• UL file No. E58048

WILMAR™ Protective Relays – WSYN Series

TERMINAL STRIPS

#6 - 32 SCREWS

• CSA file No. LR61158

Operation:

A. The output relay will energize when all three

of the following conditions are met:

1. Voltage differential is below the preset

value.

2. Phase angle is below the preset value.

3. Frequency differential is below the preset

value.

3 ¹/

B. The relay is also provided with a "Double Dead

Bus" feature: When the voltage on either one

of the sensing inputs is below 15-25% of

nominal, (Dead Bus Condition), the output

relay will energize to permit paralleling.

When both sensing voltage are below 15-25%

of nominal, the output relay will not energize.

Notes:

1. Remove black cover screws to gain access to the adjustment potentiometers.

2. Clockwise rotation increases the trip differential setting.

3. Calibration terminals (11) (12) must be connected together to disable the phase angle

detector when setting the frequency difference trip point. Once it is set, the connection must

be removed.
