Startco Earth Continuity Relay

This is achieved when all ground fault relays on the system trip at the same level with those.

Startco earth continuity relay.

Startco pty ltd is an australian owned company in incorporated in 2000 and based in noosaville queensland australia. The rob earth continuity relay has been designed to as 2081 2 1988 to monitor the earth continuity of a trailing cable in an underground mining operation. We may also collect personal data such as your name job title company name address email address and telephone number either directly from you or by combining information we collect through other sources. 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. 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. The relay has been approved to be intrinsically safe and is suitable for use in zone 1 or 2 hazardous areas. Ampcontrol remains at the top of the field for innovation in earth continuity protection relay design.

The se 502 ground fault ground continuity detector provides class a gfci trip level and trip times for personnel protection. 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. 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. As little as 5 ma of ground fault current can be detected and the internal neutral grounding resistor limits the maximum ground fault current to 100 ma.

We are a specialist electrical protection company servicing the heavy industrial and mining sectors throughout australia.
