Principle of Operation:
The JRF 014 is microprocessor based frequency relay The relay can be configured for 2 stage under frequency relay, two stage over frequency relay or Under / Over frequency relay. The relay's operating time can be programmed. The relay measures line frequency and if it exceeds the set threshold in case of over frequency or if it is less than set threshold in case of under frequency then relay extends a trip signal after an operating time.
