House AC Line Variance


A question about AC...

My measured AC line voltage runs from 123 to 130 VAC. Lowest in the evening and highest in the morning. I assume this is due to load in the neighborhood. It really affects the bias on my tube integrated.

So is this a normal range (seems high) and is that big of fluctuation?

Is this something that can be "controlled" at the house or is this the power company?

Thanks for any info.

Porziob, I disagree! The standard is 120v +/-5% [114v to 126v]. Just checked mine at 7:30 PM [TV & A/C running] and it's 122v...but we have a recently upgraded power grid in my area.
