XGN-NER neutral grounding resistor is a set of grounding equipment, including grounding transformer, which could be installed in the power system of power plant, the power supply systemof substation and the distribution system of industrial and mining enterprises. It makes these power networkscarrying out operation by usingneutral point to connect the ground through the resistance.

XGN-NER neutral grounding resistor not only can release the latter phase energy by single grounding arc to reduce the possibility of re-combustion and restrict the over-voltage of power network, but also can increase the sensitivity of relay protection device to effectively protect the normal operation for the system when the tripping happened.
