Neutral Grounding Resistors limit fault current to ensure safety of workers and equipment in electrical systems. In such a way, the fault currents that may occur may be in high enough current values to damage the generator, motor, cable or other critical elements of the facility. The neutral ground resistors used limit the current by increasing the resistance value. On LV and MV distribution networks, neutral points of power transformers and generators are grounded through a resistor.
