10.5KV 100A Transformer Neutral Point Grounding Resistor Protection Device
Product Introduction:
Neutral grounding transformers in resistance grounding resistor systems protect power transformers and generators from damaging fault currents. Low resistance grounding of the neutral limits the ground fault current to a high level in order to operate the protective fault clearing relays and current transformers. These devices are then able to quickly clear the fault, usually within a few seconds.
Main Features:
* Stainless steel grid resistor banks standard
* Dry Type Transformer
* Extra heavy duty mounting channels for transformer
* Junction box/ Terminal block for easy addition of protective relaying equipment
