280V motor on 230V circuit

I also asked about tap changers/regulators. Is this what these are, and
if so, are they likely to be manual or automatic?

in upstate NY. You may have to click on street view and rotate to see them)
Yes. Note the primaries are broken by insulators, and there is no
secondary [240/120] service on the pole. [The lowest run is TV coax, then
neutral above it.]
I've never heard of such as manual regulators so I assume they are
automatic.
It's somewhat unusual to see all three on one pole; it must be a BIG
one. Generally I see them staggered on 3 adjacent poles; or two poles
hold a platform between them.
