Description
The NewElec GA Earth Leakage relay
Provides earth leakage protection also known as ground fault protection designed to protect personnel and equipment by rapid disconnection of main supply to faulted equipment a unique feature is the integrated distinguishing between Earth leakage and Earth fault routing trips to incoming circuit breaker rather than the fault level limited main circuit contactor. Pioneers of the harmonic suppression circuit characteristics, the GA Earth Leakage protection relay enables more sensitive earth leakage protection of high kilowatt motors started direct-on-line as well as variable speed drive applications without nuisance tripping, this is achieved utilising band pass filters as well as incorporation of a screen winding on the CBCT to ensure even flux distribution under high starting current conditions.
