Just trying to understand the power company's reasoning behind this. Since December, the Local utility has been fluctuating the line voltage on a weekly basis. This is happening on all my UPS's across an entire town. For about 4 days it will be 116v, then for 4 days it will be 124v. It just cycles between the 2 voltages. I understand the day/night voltage dips with system load, but the every 4 day change has me puzzled. Unless they are regularly switching generating sources? I would have thought that at some point any generation voltage change would be evened out.
Probably just switching within the distribution system, like if they're doing line work somewhere.
If you're fed underground that adds significant capacitance to the lines compared to aerial, which limits the ability of an underground line to deliver power. If you're on a looped distribution you can end up on the near side or far side of the tie in point depending on current switching config of the distribution loop.
