Had an arc flash last weekend at a power plant, failed racking interlock on a MV breaker, huge flash. Good part is they were using a remote racking system wireless from the other room and no one was injured. Nice to know that 1 or more life may have been spared.

Thanks Zog. It's always good to hear the good stories.
Now give us some pictures and tell us the estimated energies!

Cant release details yet, but i will post when I can. I can tell you it was a nasty one based on the damages that occured to the breaker and cell. It was not contained by the switchgear.
