Features
The SE-330AU series is an advanced earth-fault and earthing-resistor monitoring relay for low- and medium-voltage transformers and generators. It monitors neutral current, neutral-to-earth voltage, and neutral-to-earth resistance. It provides continuous monitoring of the neutral-to-earth path to verify that the neutral-earthing resistor (NER) is intact. An open NER renders current-sensing, earth-fault protection inoperative and could result in a false belief that the system is functioning properly.
