Georgia Power 'Preston' Substation - Preston, GA

Georgia Power 'Preston' Substation - Preston, GA
Here is Georgia Power's "Preston" substation, which, as the name suggests, supplies the town of Preston with electric power. The voltage is stepped down from 46kV, with one transformer and a bank of three regulators putting out a single 12.47kV distribution circuit.

It appears that Georgia Power is getting ready to do some work on the sub with a trailer transformer sitting outside.

Is that a new unit transformer behind the trailer?

That's a set of three new voltage regulators. You can see them a bit better in this photo:

I wonder if that's what they plan to service/replace in this sub? Typically the voltage regulators are integrated into the little trailer subs like these.

Hmm. Could be increasing the capacity of the sub by putting in bigger regulators?

maybe it's a size increase. They're bigger than the original regulators and not connected to the trailer sub.

I'm not sure to tell you the truth. There isn't a lot of growth in this area, but perhaps an increased substation capacity could allow this 12.47kV distribution system to be looped with another nearby?
