Abstract :
Arc flash is an important consideration for personnel safety. This paper shows test results for overhead arc flash scenarios and arc flash in a padmounted switch. Both scenarios result in more incident energy than expected. For overhead arc scenarios, longer arc lengths are considered when analyzing arc flash. For the padmounted switch, an equation is developed to help coordinate protective clothing with minimum approach distances and upstream protective relaying.
