The ecm3 relay monitors a low voltage dc signal applied between the pilot and earth of the cable and by measuring this signal determines the resistance of the pilot earth loop.
Earth continuity relay schneider.
Earth continuity relay model ic3 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.
It provides earth continuity protection in accordance with as nzs 2081 ensuring the earth connection through a trailing reeling cable is maintained.
An earth continuity relay is designed to provide earth continuity protection.
A00020 earth continuity relay i c download datasheet.
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.
Is not connected to earth and the load casing is connected to earth.
The ecm2 earth continuity relay has been designed to monitor the earth continuity of trailing and reeling cables supplying power to mobile machines where there is not a requirement to comply with as2081.
Therefore an it earthing system guarantees the best continuity of service.
The ic3 utilises microprocessor technology to provide a greater level of stability over longer pilot cables by using digital filtering techniques.
B very low fault currents.
