I'm hoping someone can give me a little insight into some issues we've been having at our theatre recently. Over the last few weeks, we've been having power blips in the building.
After one, where the power flickered 3 times in a row, the next day one of our moving head lights (Mac 2000 Profile) stopped working. Upon inspection, a fuse on the PCB had blown.
Fast forward a few days, we get told by maintenance that another brief power outage had happened overnight. We immediately checked all of our equipment. I powered up my other moving lights (Techni-Lux Tracker 575) and 2 of them started vigorously shaking in place. These two fixture's power are paired together. We went to the catwalk where the power connects to the stage-pin connection for the dimming system, and the connection was completely melted.
Some info on our dimming system: We have a strand dimming system and the power for all of our intelligent lights are on non-dim/relay packs. We keep all of these circuits off unless we are using the lights. They are also programmed to turn off in the early AM in the off-chance that we forget to turn them off.
In the first instance, the fixtures were powered on during the power outages. However, the second instance, the power was already shut off to the fixtures.
I know you can't put these fixtures into surge protectors, but is there something we can do to help prevent these issues? I saw an old post on here but I know things have changed over the years.
