Product Description
Product Overview
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 such as reduced ground-fault flash hazard, minimized point-of-fault damage, and reliable ground-fault protection, ensuring a stable system not subject to ferroresonance. The monitor measures NGR resistance, NGR current, and transformer or generator neutral-to-ground voltage. It is compatible with modern resistance-grounded systems and can be used in alarm-only or tripping systems with selective coordination.
