Bender NGRM 700 Neutral Grounding Resistor Monitor and Relay
Sept 2, 2020
The Bender NRGM 700 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. It can be used to perform the functions required by Rule 10-302, Use of Impedance Grounded Systems, of the CE Code, C22.1-18, Section 10, Grounding and Bonding.
