Наружный нейтральный заземляющий резистор для генератора трансформатора 10 кв 11 12

 Neutral Grounding Resistor

Neutral Grounding Resistors (NGRs) are used to limit the fault current for safety of equipment and personnel in industrial systems.
In solid grounding, the system is directly grounded and the fault current is limited only by the soil resistance. The fault current can be very high and can damage the transformers, generators, motors, wiring and other equipments in the system. The NGRs are inserted between neutral and ground in order to increase the net resistance in the event of an earth fault and limit the current to a safe level.
