Sounds like it could be a problem with harmonics on the line?

1) Digital meter may be reading peaks instead of RMS
2) An issue could be if electronic gear is responding to these peaks - it would be interesting to attach a DC meter to the B+ in a piece of unregulated gear and see how much that varies during the day
3) Be prepared to show/tell the power co. what kind(s) of meter(s) you are using
