Using a pro DVM, not a radio shack cheapo. It seems two things are going on here, one, at least for resistive loads, if you say have a voltage of 100 volts and 1 amp, is 100 watts RMS.
So if you pump up to 120 volts and now have 1.2 amps you are consuming 144 watts.
So tell me the motivation for PP&L to put out lower voltages?
I have had many appliances die, one TV actually caught fire.
Even spiral bulbs are dying early.
So my question is this: Has anyone tried the idea of a large Buck Boost transformer, say 10 Kw rating or so, to cut the voltage by 10%? Seems that would lower the electric bill and save equipment. If I went down 10% I would now have around 110 volts. Do you think the bill would actually go down if I did that and can I do that myself or would I have to have PP&L do that and would they at all? I asked them about the voltage and they were a bit arrogant, it's in the legal limit, so basically tough luck.
What do you think about a high power buck boost transformer?

Sorry, I forgot to say the voltage on both sides were close to 123 VAC.

Do your neighbors have the same problem. Seems a little high. Cutting voltage won't reduce your electric bill, given the same appliances. Kilowatt-hours are based on voltage, current and time. Generally, higher voltage across the same load means less current. Ohm's Law and definition of power. A transformer is not 100% efficient, but may be cheaper in long run than replacing tv sets! I would check with your state public utility commission concerning delivered voltage. Do not take the utilities word for ANYTHING!
