Arc Flash Incident Assessment and Mitigation: A Case Study of Fatal Accident due to 6.6kV Bus Coupler Switch Gear Flashover at Central Waste Management System (CWMS) in PFBR

Electricity is a vital part of our modern world. Human cannot even think about a single day without electricity in life. The number of occupational electrical accidents in Indian industries declined over the last decade, but technician, worker injuries and fatalities still occurs among the country. Contemporary measures to increase electrical safety are not effective enough. In order to condense the number of electrical accidents, there is a necessity for more information about electrical accident risks at the operative level. This review presents case study of electrical fatalities due to electrical flashover in 6.6kV Bus Coupler Switch Gear at Central Waste Management System (CWMS) in Prototype Fast Breeder Reactor (PFBR) in India, its assessment and mitigation techniques to reduce similar electrical accidents.
