Bjarney, I had live voltage like that at my mom's house about ten years ago. Called the POCO, get the customer service driod, who didn't know what "voltage" meant. "Are the lights on?" "Yes" "So what's the problem?"... I told her to just write it down that I was seeing 132V, which should be 125V max, and give it to someone in their technical depts. A few weeks later two linemen with a DVM drop by and measure the voltage, yes, 132V. Bad neutral? So they measure the 240V, they get 265V. Can't blame the neutral. They go visit the local substation, found a few bad capacitors and replaced them. Still 132V (they saw that we had a good DVM and knew how to use it, so they just called on their cell phone for us to measure it). Turns out that the town's loading of the 3 phase distribution net was unbalanced. It took about a month before it was corrected.
My line is at 124V at 11:59 Thanksgiving day right now.
