Testing for Safety

摘要

ComEd conducts real-world cable fault tests to determine arc flash energy and safety blanket effectiveness. Commonwealth Edison (ComEd) conducted a survey of the utility industry on how to determine energy created during arc flash events. The limited information available focused on selecting arc-rated clothing rather than determining the parameters for calculating the incident heat energy. ComEd's research also revealed the industry was not aligned on the best methodology to use when estimating the incident heat energy. In an effort to find a better way to protect its employees, ComEd contacted the Kinectrics High Current Testing Lab in Toronto, Canada, and arranged to conduct primary underground cable and joint fault testing to measure the incident energy created during a fault. ComEd selected the Kinectrics Lab because it is the developer of ARCPRO and had the facilities to perform the testing.
