Electric Vehicles and Arc Flash | Electrical SafetyWhat is arc flash? Electrical arcing (sometimes called a ‘flashover’ or ‘arc flash’) produces heat leading to burn injuries that can be life changing or fatal. Often those working with or near electricity do not appreciate the risk of serious injury and consequential damage to equipment that can arise from arcing. A typical electric vehicle battery

Arc Flash Analysis: The Complete Step by Step GuideWhat is Arc Flash Analysis? An arc flash analysis is essentially a risk assessment of a particular environment within a workplace that determines what arc flash hazards are present.
