Generator Neutral Grounding Resistor
Neutral grounding resistors are used to protect power transformers power generators and other associated equipment in your power systems against 5060 hz faults short circuit and transient phenomena lightning. The short form of ngr is neutral grounding resistor. Monitor Device Ground Fault Protection Circuit And Neutral Grounding Resistors Industrial Electrical High Resistance Neutral Grounding Resistor Mingrui Earthing of the neutral limits the ground fault current to a high level typically 50 amps or more in order to operate protective fault clearing relays and current transformers. Generator neutral grounding resistor . Neutral grounding resistors are used to reduce problems such as insulation breakdown caused by transient over voltages produced by arcing ground faults in ungrounded systems and damage to motors and switchgear caused by arcing in solidly gr...
