IEEE Twin Cities PES/IAS Joint Society Chapter Meeting: IEEE 1584 Revolutionary Changes Coming


There are 51 people registered as of 10/11/2018.  The event can host up to 60 people.

IEEE 1584 has been the definitive guide for Arc Flash calculations since its original publication in 2002. Today its impact on the electrical equipment industry would be difficult to exaggerate. Soon the guide will be republished with significant changes to the model used for predicting incident energy, arcing current and the 1.2 calorie arc flash boundary. Rather than an evolutionary change, this upcoming edition of this important IEEE guide will be a revolutionary change in how we understand the science of the arc flash hazard.  Consultants, users, and workers need to understand the new model and what it says about the hazard posed by exposure to live electrical equipment. Mr. Valdes will present on the current draft of this standard, contrast it with the 2002 model and discuss possible effects on industry.
