WHAT IS ARC FLASH. An Arc Flash is very simply, an electrical short circuit through air. Whether it occurs from phase to ground or phase to phase doesn't matter. What does matter is that enough energy is present to perpetuate the arc. Lightning is an example of arc flash as is an electric arc welding machine. The difference between them is that lightning discharges itself in a very short period of time whereas an arc welding machine sustains the arc indefinitely. Either way, you don't want to get too near either of them.
