The presenters will provide a high-level overview of arc flash hazard and requirements by NFPA 70E – 2015. The course will present different aspects of arc flash hazard exposure and provide mitigation techniques to reduce exposure to personnel. Aramco has done extensive work evaluating how to reduce available incident energy at their facilities. Jim’s segment will review what Aramco is implementing across 1500 substations in Saudi Arabia. In addition, we will discuss recent published research on LVMCC safety improvements that reduce incident energy for open door troubleshooting to 1 cal/cm2. One of the basic tenets of a good protection scheme is fast fault clearing time.  This is especially important in mitigating arc flash energy.  Matt’s segment will explore the advantages and challenges of implementing a zone-selective interlocking scheme with protective relays to achieve those goals.
