SE-325 Series Neutral-Grounding-Resistor Monitor

The SE-325 Neutral-Grounding-Resistor Monitor is used on

resistance-grounded systems up to 25 kV to monitor the

integrity of the neutral-to-ground path and to detect ground

faults. It measures current and voltage in a transformer or

generator neutral-to-ground connection and continuity of the

neutral-grounding resistor (NGR). The SE-325 coordinates these

three measurements to detect a loose connection, corrosion,

ground fault, or NGR failure, and provides one alarm or trip

output contact.
