Sanity is pretty close on this one, but I have done this type of work, I have changed/upgraded several panels, and have also satisfied the toughest electrical inspector in Cleveland. The MOST likely problem is an intermittent neutral. The best way I can put this in laymen's terms is this, the power coming into your house is not 110, it is 220. However it is center tapped in the middle. It is the neutral at that point and it must have a connection. If not, just like when you charge mismatched batteries, it can overcharge some of them while leaving the others dead, or deader. It is rare that a problem on the grid or in a transformer would cause the voltage to spike on a regular basis. Anything like that would eventually completely fail, or if it's on the grid, would be corrected. At my shop I had been paid more then once by the power company. That is when the fault is on their end. This fault can be insidious. I know on many houses in Cleveland, the neutral is fused at the pole. This is not only unnecessary but is stupid. If the house has proper grounding and the neutral is tied to the ground, which it is in most installations, the Earthe is supplying the neutral, but it is not as good a connection as it should be. This can go on for years, and a buddy of mine had it happen. It was the neutral to the pole. Some lightbulbs alway burned out fast, and there were some other problems. He didn't call me because he knows how to check it out himself. He called the power company, and indeed they admitted that he had a dropped neutral, and in this case the problem was on the transformer up on the pole, so he wasn't the only one affected, but apparently the only one that noticed. To my knowledge anyway. People were calling electricians right and left maybe, I dunno. Thing is, that is a good option now that I think of it, they should not charge you to check their own lines. Once it gets into the house it costs money, but it may be a good idea to call them first. The problem could be outside and if it is it will be fixed for free in most places. I know here it would. Here they are responsible for the lines up to your meter box, you or the landlord take it from there. But that is here and it might not be the same there. But still I would call them first. T
