Arc Flash Hazard Study – The Basics

Arc flash hazard is a huge concern in areas where you are operating medium voltage (1kV – 34kV) and low voltage (less than 1kV) equipment. Mostly because, when you inadvertently initiate a fault, an arc flash ensuing it releases enormous amount of heat energy. The composition of this arc includes molten bits of copper or aluminium busbar or cable.
