High Resistance Grounding

High Resistance Grounding (HRG) can add the safety of a grounded system while minimizing the risk of service interruptions due to grounds, providing maximum continuity of service. Powell's High Resistance Ground systems are available for both 600V and 5kV systems. Units can be constructed as stand-alone cubicles or installed integral to low voltage or medium voltage switchgear.
