NEUTRAL GROUND RESISTORS

Neutral Grounding Resistors serve a crucial role in electrical systems by restricting earth fault currents. Their primary function is to protect generators, ensuring operational continuity and the safety of both personnel and equipment. These resistors ground the neutral points of power transformers and generators in LV (Low Voltage) and HV (High Voltage) power distribution systems. By limiting fault currents, they effectively prevent high current values that could otherwise cause damage to generators, motors, cables, and other essential equipment, guaranteeing system safety and uninterrupted operation.
