Description

The SE-330HV is a microprocessor-based neutral-grounding-resistor (NGR) monitor designed to detect NGR failures and ground faults in resistance-grounded systems. It offers advantages over traditional grounded systems by reducing ground-fault flash hazards and minimizing point-of-fault damage. The SE-330HV is suitable for modern resistance-grounded systems, including alarm-only and tripping systems, and is compatible with specific sensing resistors and current transformers for comprehensive monitoring.
