Frequency monitoring relay

Frequency monitoring relays are specialized protection devices designed to continuously measure and supervise the frequency of AC electrical systems, typically within a range of 0 to 1000 Hz. These relays, often referred to as frequency relays or frequency supervision relays, are critical for detecting underfrequency or overfrequency conditions ...
