Up the street from me, they upgraded a MV distribution circuit
from a lower voltage to a higher one (13,800V I believe).

Have they been adding on to the circuits in your area? New buildings,
etc? What was the previous voltage?

No new construction/new loads in that area. It may have been done to
allow that circuit to provide an additional 13.8K feed to a medical center
a ways upstream. I am uncertain of the old voltage but the nameplate for a
regulator transformer on a nearby old circuit reads 2400V which seems kind
of low. The utility seems to have been upgrading other older/lower voltage
circuits in the area as well.

In my neighbourhood the top line is usually 1600V, with one or a few
pole pigs per block to make 120-0-120V. Of course we're about half a
mile from the substation.

The top line running down my street is 7200 volts. Maybe that's
because I live in a rural area. It seems high to me but the guy from
PSE told me that it is not unusual, at least where I live.
