Please plan to attend this meeting of the Industry Applications Society. The speaker will be Albert Marroquin, P.E., V.P., Electrical Safety & Dynamics, Senior Principal Electrical Engineer, ETAP. 

The revision process of IEEE Std. 1584 Guide to Performing Arc-Flash Hazard Calculations is almost complete! The revision includes the new arc-flash model; which is the result of the NFPA and IEEE collaboration effort to improve the accuracy of the incident energy calculations. The new model includes the effects of both horizontal and vertical conductor orientations (VCB, VOA, VCBB, HCB and HOA), plus refined models for arc current variation and enclosure size effects on the incident energy. The presentation will feature first-hand insight into the background on the laboratory testing and model development to help engineers understand how and why the arc current and incident energy results may be different. Furthermore, discussion will take place on what is perhaps the most difficult application consideration of the new model; which is the detection and classification of actual equipment into one of the five electrode configurations.  Last, some quick pointers on how the new model is to be applied in power system analysis software will be provided. 

The seminar will be presented by an individual intimately familiar with the arc-flash standard revision and standard, Albert Marroquin, IEEE P1584 New Arc-Flash Model Validation Task Group Vice-Chair and Ballot Resolution Committee Co-Chair, who actively participated in the model refinement and validation.
