The NGRM750 Neutral Grounding Resistor Monitor detects grounding-resistor failures and ground faults and monitors line voltages. It is intended for use in low-resistance grounded (LRG) commercial and industrial power systems. It is an advanced device that allows monitoring of :
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 designed for easy retrofit with a panel mountable human-machine interface (HMI). If preferred, the relay can easily be programmed via the built-in webserver. NGRM750’s can easily connect to a supervisory system with Modbus TCP/IP or RTU communications.
For generator or transformer grounding applications at extreme altitudes, the NGRM750 features a 5,000 m above sea level capability.
It is an ideal solution that is easy to retrofit into existing LRG applications or factory-install in new LRG packages. Capabilities extend to 25 kV and 2,000 A.
