Electrical safety - arc flash hazard analysis Bhatia Sanjeev Member, IEEE and Member, CIGRE Online published on 15 October, 2020. Abstract Arc flash safety is one of the most important aspect while handling switchgear in the electrical distribution system. Recently there has been continuous effort within the manufacturing industry as well as in the plant operations to determine the level of arc flash hazard, the mitigation techniques, and the methodologies for equipment labelling and safe working. There are different International codes and standards like OSHA, NFPA, and IEEE which establish different guidelines to enhance electrical safety. The paper covers different aspects as mentioned in these codes with respect to quantifying the arc flash hazard by calculating incident energy levels, establish flash protection boundary and identification of personal protective equipment (PPE) requirements. The paper also elaborates on different mitigation techniques to reduce the arc flash hazard that may be employed during the engineering phase. Top |
