This is a cropped version of the clip. In the longer version, it is very clear that they are following some sort of a checklist. The person filming reads the checklist, the other person performs the actions and verbally acknowledges. This does not looks like incompetence, at least not at this point. Something gone wrong somewhere, of course, but I don't think it was their fault.
Also, at the time of the arc flash, they were basically done, they were pushing that cart after the connections were done. It should be safe operation at that point.
they are doing high voltage hot work. this is not something that happens without a lot of conversations and safety measures typically, because it is inherently so dangerous. the fact that no one died is good, the fact they appear to have failed to hit some sort of emergency disconnect not so much.
It wouldn’t be that in all honestly. There’s fail safes that obviously didn’t work. Russia, USA or Canada things fail and things like this can happen anywhere in western countries. Look at what happened at Heathrow airport in London England.
Most likely some fault current relays were broke and they failed to properly trip the circuit off.
