I'm helping a school with some upgrades to their lighting system and a big issue is that recently the school was struck by lightning and it has started causing intermittent issues with the dimming system. It's a dimming rack with conventional fixtures, about 20 years old. Some circuits don't work at all, and some fixtures will keep blowing after being used for a day or two. My guess is some conductors were welded together and bringing stuff up will overamp the circuit. Potentially phase crossover even? It sounds like some nasty stuff is going on.
Obviously they want to fix this but to me it sounds like Electrician (with a capital E, i.e. commercial/certified) territory. However, I don't know if they will want to get involved in a theatrical system.
We might end up replacing the dimmer rack, but I wouldn't want to put in a new processor and everything without assurance that these issues won't keep happening. So it is necessary to ferret out where specifically the damage is.
Can anyone provide some insight about where to start or what to look for? The school staff does not really have the knowledge to help much.
Thank you.
