Jim Phillips, PE
Topic: DC Arc Flash Calculations and Studies


Rectifiers, Photovoltaics, Battery Systems, DC power is everywhere. And with it, the possibility of a DC arc flash.

When IEEE 1584 Guide for Arc Flash Hazard Calculations was first published in 2002, it did not consider DC arc flash. Subsequent to the 2002 Edition, several technical papers have been developed regarding DC arc flash and calculation methods.
Join us as Jim Phillips, P.E. founder of brainfiller.com, ArcFlashForum.com and Secretary of the IEEE 1584 working group takes you from the history of DC arc flash up though the calculation methods. By using a series of examples, Jim will walk you through the DC arc flash calculation process.


• History of DC arc flash technical papers
• Need for DC arc flash calculations
• DC arc resistance calculations
• DC arc power and energy
• DC incident energy calculations
• DC arc flash calculations – open air
• DC arc flash calculations – enclosures
Biography: With a career spanning over 30 years, Jim Phillips has taught tens of thousands of people from around the world understand electrical power system design, analysis and safety. He is the founder of www.Brainfiller.com and www.ArcFlashForum.com

Jim literally “wrote the book” about arc flash studies with “Complete Guide to Arc Flash Calculation Studies” Jim is Secretary of IEEE 1584 and is the Liaison Officer of the IEC working group 13 based in Europe. He is a regular contributor to Electrical Contractor Magazine.

John Kim of EnerSys

The reliability of battery backup systems is critical in maintaining the robustness of infrastructure. Telecommunications, UPS (Uninterruptable Power Supply), and Utility sectors all rely on battery power backup systems to communicate, control, and power mission critical equipment. This presentation will identify and understand the variables that can affect the lead acid battery’s reliability and life. It will also examine the pros and cons of alternate battery systems.

Biography: John Kim has been in the standby battery industry for over 25 years. Currently, John is a Director of Technical Marketing at EnerSys. He has written numerous papers and presented at many industry related conferences including Battcon, Doble, Eurobat, Intelec, Infobatt, and IEEE chapter meetings. His battery background includes R&D, manufacturing, product management, and technical support. He is also knowledgeable in battery selection, specification, maintenance, and troubleshooting. John received both BS in Materials Engineering and MS in Engineering Management from Drexel University.
