Neutral Grounding Resistor

INDUSTRIES SYNDICATE’ make NGRs is an electrical device used in power distribution systems to limit the fault current that can flow through the neutral conductor of a power transformer or generator.

Description

INDUSTRIES SYNDICATE’ make NGRs are rated upto 33KV.Single line to ground faults are tripped off immediately.This is one of the widely used form of system grounding. Usually neutral of substation transformer upto 33kv is grounded through a resistor called neutral gounding reistor. Ohmic values are so selected as to relieve the system of destructive transient voltages.
