High resistance grounding— medium voltage - Eaton
WEBThe concept behind high resistance grounding is to pro vide a path for the ground current to flow while limiting its magnitude by using a resistor. The ground current path is provided at the point where service begins. Control equipment continuously monitors the magnitude …
Neutral Grounding Resistor (NGR) - Neutral Earthing Resistors
- Typically, N G Rs are used in conjunction with generators or motors. With both of these devices, ground fault currents can be extremely high and if not controlled can result in damage to transformers, generators, motors, wiring and associated equipment. Moreover, neutral grounding resistor for generators will avoid damaging the stator core. Stator ...
