NGRM700 (HRG), NGRM750 (LRG)
Intended use
The NGRM700 is only intended for use in high-resistance
grounded systems. The NGRM750 is only intended for
use in low-resistance grounded systems. In these sys-
tems, the NGRM7... monitors
• the current through the neutral grounding resistor
(NGR),
• the voltage between the star point of the transform-
er and ground (voltage drop across the NGR),
• the condition of the NGR,
• line-to-line and line-to-earth voltages.
