Electric arc Spark of interest
One of the workers was fitting cables in the back of the capacitor, which was positioned above a number of live conductors. The cables came into contact with one of the conductors and caused an electric-arc flashover. The worker suffered severe burns to his face and upper body horrific injuries that have prevented him from returning to work.
