Frequency Sensitive Relays

WILMAR™ Protective Relays – 25-000 Series

Function:

81 O/U

•

ANSI/IEEE C37.90-1978

The output contacts of frequency relays are ener-

gized when the frequency exceeds the adjustable set

point. Overfrequency and underfrequency relays are

available in 50, 60 and 400Hz. Combination over/

underfrequency “band pass” relays are also avail-

able. These are energized at rated frequency and de-

energized during overfrequency or underfrequency

conditions. Frequency Differential relays are ener-

gized above the preset frequency. The pick-up and

drop-out frequency settings are independently ad-

justable.

#6 - 32 STUDS

6 PLACES

Operation:

The normally open contacts close, and the normally

closed contacts open, at nominal frequency. The

contacts are de-energize at underfrequency,

overfrequency or no input voltage.

Notes:

The contacts are shown in the de-energized position.

Remove screws for access to the underfrequency and overfrequency trip adjustments.

Clockwise rotation of the adjustment potentiometer will raise the frequency trip points.
