The last remaining 2400V step-down on this muni's system, but the presence of a switching pedestal for the 12.5kV system is a bit troubling.

Not too often when I see a sub where the 'transmission' voltage is 12.47kV.

Any ideas on how many customers are served out of this sub perhaps?

There's a small portion of the northeast part of town left on the 2400V system. The factory just to the east was moved to the 12.5kV system some time back - there was a big scaffold bank that's been converted into a riser. I should get a pic the next time I'm down that way.

I really need to get to Choptank Electric's Barclay Substation! A branch from a Delmarva Power 25kV line is on co-op poles and enters a 25kV to 12.5kV substation which power's most of east-central Queen Anne's County.

I spy a set of older black cans in the back- they look almost too big to be regulators. Interesting to see a metering rack on that back pole. Looks like it's been out of service for some time.

I'm thinking they moved those gray step-down cans from one of the others that was torn out, but yes, those are the old step-downs, and I'd think that was the first step-down installed after the muni went on the grid (as if they were served through Union Electric Coop before getting their own sub on East River's system).

Come to think of it, this is somewhat similar to Lakota's. www.ipernity.com/doc/ndlinegeek/36886104
