Topic Title: So how long does a transformer replacement take?
Until they get done?
I worked for one of the local electrical utilities for several years, and watched many transformer swaps. There's no one right answer except the one I gave above.
There are way too many variables.
Was the pole damaged to the point where it needs to be replaced? IF so, add at least a couple of hours...maybe 8, depending on the number and voltage of the lines attached to it.
Just a "simple" transformer replacement? SHOULD be only a couple of hours, but again, too many variables.
Location of said transformer, availablility of a replacement, distance from the location of the transformer and the yard where they store replacements, etc.
Some crews carry a couple of the more common pole transformers with them to save the time of running to get a replacement, but it never fails, one that's out in the boonies with crappy access, will be an uncommon model, that they MIGHT have 1 of in their storage yard...
Here's to the guys (and gals) who work in all kinds of shitty weather to keep our electricty turned on...
