Neutral Grounding Resistors are incorporated into electrical circuits to protect the system and devices. Neutral grounding resistors protect electrical circuit components by limiting the ground fault current to an acceptable level.
Within three phase electric voltage system, the neutral branch is referenced to ground (earth). In the event that a current fault occurs (short to ground), extreme current causes by the fault will damage electrical circuit system and components. By installing a neutral grounding resistor, the faulty current will be limited to a predetermined level.
