New utility engineer; looking for a good overview of distribution
(OP)
I got a job with an Electric Utility company and haven't been given a ton of direction/training, and am finding I'm having to study/train on my own to understand the various parts of the distribution system. I've looked at several websites and powerpoints that give BROAD overviews, but am looking for something that digs a little deeper into the specifics. Especially when it comes to overcurrent and overvoltage protection (arresters, cutouts, fuses, etc).
Are there any good resources you guys can recommend?
And for a quick specific question: When an arrester successfully diverts lightning to ground, protecting the device it's in parallel with, once the lightning surge is over, the arrester returns to its normal high-resistance state? I've read about some arresters blowing a charge out the bottom but am unsure when this actually occurs, and under what circumstances.

My good buddy Jonathan Woodworth has an excellent site on arresters. Search for Arresterworks. I'm sure he's got material on this.

Magoo2, when the .22 isolator disconnects the ground lead, after the arrester experiences a surge that overwhelms it (from my understanding), that means the arrester is no longer functional (since it can no longer divert the surge to ground), and that the device it's protecting is now unprotected from overvoltage conditions; correct?

Once it takes the arrester out of the circuit you have no protection after that.
