Using Technology to Minimize the Arc-Flash Hazard

An article in the IAEI Magazine (International Association of Electrical Inspectors) discusses some of the technologies available to minimize arc flash hazards. The article focuses on current limiting devices and high resistance grounding. The final paragraph summarizes the article:

"High resistance grounding systems do not protect against the less frequent but still dangerous phase-to-phase or three-phase arcing faults. However, the combined use of high resistance grounding for protection from ground faults and its ability to prohibit the escalation of the fault and current-limiting fuses or current-limiting circuit breakers for phase-to-phase and three-phase arcing faults is an effective engineering approach to minimizing the arc-flash hazard."
