Advancements in technology create safer & smarter HRG systems

The merits of high resistance grounding (HRG), design considerations, and potential safety issues, prior to its application have been well documented in past Electrical Safety Workshops. At the 2008 IEEE Electrical Safety Workshop, a challenge was put forth to discuss current and developing technologies that can resolve some of the potential safety issues. A field survey was conducted and research was performed to identify these issues. This paper discusses each potential safety issue and cross-references it with a current or developing technology to assist the user during the design, operation, and maintenance stages. These advancements in technologies have the ability to resolve the potential safety issues, establishing a safer, smarter HRG system.
