Dimming lights

No, I don't think it's acceptacble. The voltage should be held at a steady state. If I were you I would remove the dimmers, just temporarly, and replace them with single pole switchs. Now measure the voltage like you did, monitoring it, and see if you still get the swings in voltage. If you don't, then you'll know it's caused by the dimmers, possibly the common neutral interataction I referred to.

Let us know what the power company says, could be anywhere, hopefully on their side.
