I didn't realize that the long-idle station service transformer behind the plant was a VERY early cooperative-style unit - note the "REA / CO-OP" stenciling.

I'd suspected I'd seen some glass in the air and I wanted to be sure... I was right. That's a CD 112 Brookfield 'keg' supporting the 6.6A loop.

After failing to find the new Leola 115/41.6kV substation, I made a quick detour to get a picture of the substation on the north edge of town once I realized the distribution here is 7200 delta! Sadly, MDU was well underway with preparations to convert the distribution system to 12.5kV Y, served from a new substation south of town. The substation today: maps.app.goo.gl/fwBz2KubX6sXP9hz7

I wasn't sure what I was looking at, but it seems MDU replaced the pole and sawed up the arm from the old one without bothering to unlink the suspensions or untie the insulators. It now looks like that the line going off to the left will be removed later.

The last time I passed the little hamlet of Holmquist, I thought I'd briefly glimpsed a Westinghouse transformer, and after quickly doubling back this time, I was correct, as Westinghouse transformers are rarely seen on this company's system. And yes, the ever-present cloud cover chose to part for a while in the late afternoon...

Looks like WAPA and the Flandreau municipal are almost done getting ready to bury the backup line. Glad they haven't touched those big GE pellet arresters... yet.

Checked on the line into Trent; this is the west end of the last segment that has not yet received a 100% rebuild.

A recent picture of the South Sioux sub. Sure looks different without the 4160V wing and the shrubs that once stood along the fence.

A view of the 12.5kV/4160V transformer on the mountain line, retired after the rebuild to 12.5kV reached the park. It now seems that as of November 19th, the conversion of the 2400V and 4160V distribution systems and the 22.9kV transmission line into one long 12.5kV/7200V Y circuit has been completed, the last section being the line along Waltonia Road.

A close view of the ancient GE fluted can. Definitely a museum piece! I strongly suspect it's the same style as the one Mike Parker photographed many decades ago: www.ipernity.com/doc/ndlinegeek/48627488
