Startco Earth Continuity Relay

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

Startco earth continuity relay.

The relay has been approved to be intrinsically safe and is suitable for use in zone 1 or 2 hazardous areas. Earth continuity monitors also known as ground check relays or pilot wire monitors are used to monitor the integrity of the earthing circuit external to the ner. This is achieved when all ground fault relays on the system trip at the same level with those. Relay coordination time selective coordination.

The se 502 ground fault ground continuity detector provides class a gfci trip level and trip times for personnel protection. We are a specialist electrical protection company servicing the heavy industrial and mining sectors throughout australia. When short circuit between the pilot and earth cores in the trailing cable completes the circuit through the operating relay and if the pilot circuit were not to fail to safety such a fault would cause the motor to start immediately.

The relay is housed in a sprecher schuh enclosure with three led indicators. In fact if the motor was running it would become impossible to stop it using the pilot switch. Since ground fault current is controlled to a level that will reduce fault damage and an arc flash will not occur time selective coordination can be employed. Startco pty ltd is an australian owned company in incorporated in 2000 and based in noosaville queensland australia.

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.
