Arc Flash Hazards: Understanding the Risks and Implementing Protective Measures

Overcurrent faults, including short circuits, pose a significant threat within electrical systems. Beyond equipment damage and system outages, these faults can also lead to a dangerous phenomenon known as an arc flash. Arc flashes are intense electrical discharges that generate extremely high temperatures and a powerful pressure wave. This article explores the dangers of arc flash events, highlights the importance of arc flash hazard analysis, and discusses various protective measures to minimize the risk of injury.
