Mingrui Neutral Grounding Resistors are designed to be used in Industrial Power Systems for added protection against ground fault currents. In the event of a ground fault, the fault current is limited to a safe value by means of Mingrui resistors. Designed and tested in accordance with IEEE standard 32-1972 Enclosure Description The Neutral Grounding Resistor will be placed in outdoor rated NEMA 3R, heavy duty, aluminized steel enclosure with provisions for easy lifting and maneuvering(for lift or crane).
