Webinar – Utility Short Circuit Current Data, Arc Flash Studies and Change<\/strong><\/h2>

by Jim Phillips, P.E.<\/p>

[See more about Jim Phillips]<\/a><\/span><\/strong><\/p>

\"AguaIt goes up, it goes down, sometimes it is thought to be infinite (although it really isn\u2019t!) and other times it seems impossible to find. \u201cIt\u201d refers to the available short circuit current from the electric utility which is one of the more important pieces of information for an arc flash hazard calculation study. Used to help define the severity of an arc flash hazard, it represents the magnitude of current that could flow from the electric utility during a short circuit.<\/p>

The available short circuit current is one of two main variables used in performing incident energy calculations. Why would the utility short circuit current change? Why would it change? Who\u2019s fault is it if it affects the results of a study? How can you stay one step ahead of the possible changes?<\/p>

This webinar is based on Jim Philips\u2019 experience in both arc flash studies, his work with the IEEE 1584 working group, Europe’s IEC TC78-Working Group 15 – Arc Flash Protection and also from experience earlier in his career as the head of the short circuit studies group for a large public utility system.<\/p>
