Earth Continuity Relay

The ampcontrol earth continuity relay ensures safety and as nzs2081 compliance through a new method of earth continuity protection that uses a trip curve to discriminate between earth disconnection faults and incremental increases in the earth return impedance that occurs due to equipment degradation.

Earth continuity relay.

The bramco electronics earth continuity relay model i c has been designed to monitor the continuity of the earth cir cuit in a supply cable by grounding the pilot core via a diode polarized positive to earth. The ic3 utilises microprocessor technology to provide a greater level of stability over longer pilot cables by using digital filtering techniques. The method used is called pilot earth loop or earth continuity monitoring where an additional core pilot cable is included with the power and earth cores in the trailing or reeling cables which supply power to the machines. Earth continuity failure protection.

The bramco ic3 earth continuity relay is designed to actively monitor the resistance of the pilot earth cir cuit in a supply cable by diode termination. As such the operating relay and the contactor will therefore open. An earth continuity relay is designed to provide earth continuity protection.
