Neutral Grounding Resistor Monitor

Intended use

The NGRM700 is only intended for use in high-resistance earthed sys-
tems. In these systems, the NGRM700 monitors
the current through the NGR,
 
the voltage between the star point of the transformer and earth
 
(voltage drop across the NGR),
the condition of the neutral grounding resistor (NGR),
 
line-to-line and line-to-earth voltages.
 
