A few years ago, the term “arc flash” crept into our electrical technical vocabulary. Since that time, performing arc flash calculations remains a challenge for many of us. Calculating incident energy ...

Methods for calculating the incident energy of an arc flash and for establishing the arc flash boundary in three-phase ac systems are addressed. It also covers the analysis process from field data ...

When working on energized equipment, electricians and maintenance technicians can find themselves in a catch-22 situation: Wearing too much personal protective equipment (PPE) can impair movement or ...

In the 2012 National Electrical Safety Code, the approach for arc flash below 1,000 V has changed. Now, utilities will have to review arc flash on distribution secondary equipment. The two main ...

“When I looked back and saw that I had no pants on the back of my legs, and literally, the skin was hanging off my arms and my legs, I just knew something horrific had happened.” So begins the story ...

Arc flash is defined as an explosive release of energy caused by an electrical arc. Typically, the arc results from either a phase-to-ground or phase-to-phase fault created by many possible events.
