MINGRUI offers high resistance grounding equipment for wye connected generators. Our equipment is normally designed to limit the line-to-ground fault current to blow 15amp for generators rated up to 14,400 volts. These units will provide a high resistance neutral during a fault condition, while allowing the system to operate as an ungrounded system during normal operating conditions. The configuration basically consists of a dry-type single phase transformer with a resistor connected across the secondary. The primary of the transformer is then connected between the wye point of the generator and ground.
