Arc Flash Hazard Calculation Studies

Posted on February 26, 2012November 22, 2019 by Jim Phillips

In the earlier years of NFPA 70E and the emergence of arc flash protection requirements, many people would use the NFPA 70E Hazard/Risk Tables to determine what arc rated PPE to wear. This approach continues to shift towards the use of arc flash studies involving incident energy and arc flash boundary calculations based on IEEE 1584. Continue reading →

Predicting the Arc Flash Duration

Posted on September 30, 2010July 9, 2015 by Jim Phillips

Determining the arc flash duration is the most important piece of information in predicting its severity. The arc flash duration is usually dependent on how fast an upstream protective device will trip. The longer it takes, the greater the incident energy and resulting hazard.
