1. Product Function
THT-ZT neutral grounding resistor cabinet (NGR or NER) are employed in medium-voltage AC distribution networks to limit the current that would flow through the neutral point of a transformer in the event of an earth fault. It connected between the neutral point of the transformer and the earth. Its function is to limit the single phase ground fault current to a specified value so that protecting the transformer and generator.
