It goes up, it goes down, sometimes it is thought to be infinite (although it really isn’t!) and other times it seems impossible to find. “It” 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.
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’s fault is it if it affects the results of a study? How can you stay one step ahead of the possible changes?
This webinar is based on Jim Philips’ experience in both arc flash studies and his work with the IEEE 1584 working group and also from experience earlier in his career as the head of the short circuit studies group for a large public utility system.

Jim's Bio:
Jim Phillips has taught tens of thousands of people from around the world understand electrical power system design, analysis and safety throughout his 30 plus year career. He is the founder of Brainfiller and ArcFlashForum.
Jim is Secretary of IEEE 1584, Liaison to the International Electrotechnical Commission Working Group 15 based in Geneva, Switzerland for arc flash related standards and active with many other national and international standards.
He literally “wrote the book” about arc flash studies with “Complete Guide to Arc Flash Calculation Studies” . He is also Contributing Editor for Electrical Contractor Magazine in the subject of Arc Flash.
Jim continues to travel the globe typically flying over 150,000 miles a year to work with various U.S. and international standards organizations and speak at many conferences and training events.
