The NGRM550 Neutral Grounding Resistor Monitor detects grounding-resistor failures and ground faults. It is intended for use in low-resistance grounded transformers and generators used in commercial and industrial power systems. In these systems, the NGRM550 monitors:
A benefit to many users is the multilingual user interface that allows the comfort of reading values and programming in your native language.
It is an ideal solution that is easy to retrofit into existing LRG applications or factory-install in new LRG packages. If customers prefer, they can easily program the relay via the built-in webserver. NGRM550’s can easily connect to a supervisory system with Modbus TCP/IP or RTU communications. Capabilities extend to 25 kV and 2,000 A.
