Earth Continuity Relay

As such the operating relay and the contactor will therefore open.

Earth continuity relay.

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. Earth continuity failure protection. An earth continuity relay is designed to provide earth continuity protection. Ampcontrol remains at the top of the field for innovation in earth continuity protection relay design.

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. 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. We took a fresh look at earth continuity safety and as nzs2081 compliance to design a new method of earth continuity protection that utilises a trip curve to discriminate between earth disconnection faults and incremental increases in the earth return impedance.
