I have avoided this thread .... simply because HV stuff is beyond my competence.
Were I asked to work on HV gear, my answer is simple: NO. If I were told it was part of my job, I would insist on training ... and the training ought to be more than 'take this tool in there and twist the widget." Anyone who claims it's simple, any moron can do it - let them show you!
As an example, I recall the time the PoCo had to kill a transformer to a grocery store. After swinging the cover open, there was a plain steel panel, with only a simple switch handle visible. Did they just flip the handle? NO. The put on PPE, extended the hot stick, and turned the handle from 10 ft. away! One has to conclude that there were reasons for these precautions.
When it comes to HV, I don't even know how to flip a switch!
