NGRM700 monitors the neutral grounding resistor in a high-resistance grounded (HRG) system. RC48C evaluates the protective conductor loop and residual current in a trailing cable with a pilot wire. These products focus on different measuring points in the distribution system and mobile load.

Monitors the neutral grounding resistor’s resistance, the fault current through it and the NGR voltage in an HRG system. Provides alarms and status information on resistor deterioration and earth faults.

Monitors protective conductor loop continuity in trailing cables with a pilot wire. Also evaluates residual current with a suitable measuring current transformer; open circuits, high resistance and short circuits are monitored according to the selected connection arrangement.
The diagrams show functional information flow. NGRM700 monitors the neutral grounding resistor; it is not a general-purpose earth electrode resistance tester. For RC48C, the pilot wire, termination unit, current transformer and switching arrangement are selected together according to the manufacturer’s connection diagram for the relevant variant.
