Unfortunately, the lighting wasn't the best here. But if you look close, you will notice an older transformer that is stepping 4.8kV up to multigrounded 13.2kV single phase, for a 23kV distribution system. Interestingly enough, it is identical to this one put up in Litchfield:

Seeing how these two cans clearly predate the risers they are connected to, I wonder if they were part of a small substation at one point?

Would be nice to see where the nameplate is on these things. and yes I think it had to have been a small sub at one point - maybe for a small industrial complex?

I'm thinking either that, or they may have been used for an early stepdown bank in a portion of the grid that was upgraded from 4800 to 13.2kV or 23kV. All of HELCO's old stepdown cans from the 60's were 13.2 at primary if I remember right, and would be hooked up in delta on the multigrounded 13.2 and in wye on the 23kv.
