Resistance Grounding

Littelfuse offers a variety of resistance grounding/NGR monitoring products that work by limiting the fault current so it does not cause unwanted fault damage, but still allows the protective relays to work as designed. These high-quality products prevent many of the problems that are associated with ungrounded and solidly-grounded electrical distribution systems. They also monitor the neutral-to-ground connection. These units can limit point-of-fault damage, eliminate transient overvoltages, reduce arc-flash hazards, and provide adequate tripping levels for selective current-based, ground-fault detection.
