Cam, there are voltage drops in the commercial power lines just as in your
house wiring. the drop is related to the resistance times current. The
farther you live from the power source, the more resistance in the circuit.
The
more current demand from you and all of your neighbors, the higher the
voltage drop.
The power company is unable to adjust the voltage to individual homes as
the current demand fluctuates and this causes your line voltage to fluctuate
as well.
There are standards that the power company is required to meet and their
engineering department can discuss these with you. The voltage fluctuation
you mentioned is on the order of +/- 5% and that is not at all unusual,
especially if you live in a rural or semi-rural area with service via lengthy
lines. I see these kinds of fluctuations between cooler mornings and hot
afternoons at my ranch location on a daily basis.

High all, I've noticed the HV varying between 3000 and 2700 volts
depending on the time of year where I live. I'm reading 234 VAC on
the line to the amp and I'm on a 20 amp 220 VAC breaker. Is this drop
a demand issue? Anyone else notice this? I've never had this issue
until I moved to this house....2 months ago.
Thanks and 73,
