BHRG Series 1- HRG systems are the simplest of Bender’s series of grounding resistors. Integrate a neutral-grounding resistor (NGR) assembly with optional pulsing function, NGR monitoring, individual ground-fault detection. Low voltage

NGR monitoring is with an RC48N Ground-Fault & NGR Monitor or an NGRM700 Neutral-Grounding-Resistor Monitor. The former provides basic AC ground-fault and open-NGR detection. The latter adds AC/DC ground-fault detection, harmonic analysis, two ground-fault detection levels, NGR-short detection, phase-voltage monitoring, and a graphical display.

Bender RCM420 or RCMA423 ground-fault monitors provide monitoring to detect AC and mixed AC/DC faults through the NGR. Bender RCMS460 or RCMS490 ground-fault monitors provide multiple-feeder monitoring to detect AC and DC faults in up to 12 circuits per device. The RCMS460 has common relay outputs; the RCMS490 adds dedicated relay outputs for each monitored channel.

Options include an audible alarm and a neutral-disconnect switch, seismic rating
