Expert View: Arc Flash Risk and Safe Isc Testing
Today, I witnessed an arc flash while a worker was attempting to measure the Isc of a PV string using a DMM. It was a horrific sight seeing. I would like to know, from an expert's perspective, what the safe procedure is for measuring the Isc on a PV string with a rated voltage of 1,369.42 VDC.
