Quickstart
NGR monitor
Intended use
The NGRM700 is only intended for use in high-resistance earthed sys-
tems. In these systems, the NGRM700 monitors
the NGR rated current,
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.
