The NGRM700 is an advanced device that allows continuous NGR monitoring to provide all necessary information of the system grounding.
The NGRM700 monitors the resistance value of the Neutral Grounding Resistor (NGR) and the fault current flowing through the NGR in High Resistance Grounded (HRG) systems. The ideal relay to protect HRG systems and to provide a comprehensive overview. The relay can be connected to the supervision system or directly to the communication network.
The NGRM700 allows the user to meet local requirements.
