ABOUT THIS SEMINAR

• New incident energy equations in the 2018 edition of IEEE 1584 mayprovide different results than existing arc flash studies. Learn what“electrode configuration” means for the data collection step of yournext analysis. Learn the new technique available to take advantage ofthe current limiting ability of modern-day fuses. 
• Learn why NFPA70E dropped the 240V exception for arc flashanalysis and what the change to IEEE1584-2018 will require.• Gain insight into what is meant by “exposed to the arc flash hazard”and who may be affected.
• Review strategies for improving short circuit safety and minimizingrisk 
• Do some of your circuits have incident energies greater than1.2 cal/cm2 even when protected by dual element Class RK1 or Jfuses? Or Class L. Learn what options you have to lower energies to“Category 0” Level. 
• Can your storeroom enhance your electrical safety program? Review asimple “5S” program to ensure safe fuse replacements.

THE PRESENTER

Mike Lang, Principal Field Engineer for Mersen, has participated in over1,000 arc flash tests in Mersen’s high power test lab as leader of theMersen arc flash team. He has coauthored several prize-winning IEEEpapers on arc flash including papers at the 2006 PCIC Conference, the2008 PPIC Conference and 2016 PPIC Conference. He was also awardedthe 2011 I&CPS Ralph H. Lee Department Prize Paper Award for his workon 208V arc flash research. He recently received the 2018 Technical Awardfor Excellence in Prevention Through Design by the Electrical SafetyCommittee of the IEEE Industrial Application Society. 

Mike is currently co-chairman of the IEEE/NFPA Collaboration on ArcFlash Research effort and has served as a member of the Research, Testand Planning Committee and on the Technical Advisory Committee as partof Mersen’s Platinum sponsorship of the Collaborations research. Mike isan active member of the IEEE 1584 Working Group.
