Earth Continuity Relay

Due to a fault in the distribution system or line or if the power to the area is switched off for any reason the supply to the transformer and thus to the pilot circuit will cease.

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 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. 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. Ampcontrol remains at the top of the field for innovation in earth continuity protection relay design.

The ic3 utilises microprocessor technology to provide a greater level of stability over longer pilot cables by using digital filtering techniques. An earth continuity relay is designed to provide earth continuity protection. Earth continuity failure protection.
