We had a black out test the other day on the ship I am on. The generator was shut with the Emergency Stop button, and after we had the ship up and running again, one monitor to the integrated alarm system was dead, and a CCTV control box (which was not the first box to go, I'm told)
What happens during a black out, is it a voltage spike that kills random (poorly designed?) equipment? Or is it a slow surge that does the trick?
And when we are looking for 24V DC earth faults, we have to switch off some breakers, cutting power abruptly. Does this off-switching cause a spike, or surge? Neither?
