MRF3 – Frequency Relay

The MRF3 is a universal frequency relay and contains the protective functions required by most electrical utilities for mains parallel operation of power stations: • Four elements for over- or under frequency protection • Two elements for frequency gradient supervision df/dt • Fast decoupling of the generator from the grid at mains failure • Suitable for load shedding systems
