DESCRIPTION
This Arc Flash/Short Circuit Study course is designed to provide a comprehensive and systematic understanding of arc flash hazards, prevention, electrical safety, calculation and analysis. It is also designed to provide the detailed steps required to perform an arc flash study. Participants will learn how to perform in depth calculations of incident energy, arcing current and flash protection boundaries based on the various methods of NFPA 70E and IEEE 1584. There will also be a demonstration of how to perform an Arc Flash study using a commercially available computer program.
OBJECTIVE
