Well, I went back to the site today to do a follow-up. I went through the main panel at the meter and checked all connections and looked for any other signs of problem. However, no visible signs and no loose connections. I then went in the house and checked the panel in there again. (This is a rural location that has a pedestal with meter and main then splits off to house and barn.) The phase terminals on the panel in the house were a little loose but not enough that should cause problems. The neutral however was relatively tight. I was able to put a little torque on it but not much.
I then called the PoCo. I explained to them what we were facing. I got the usual, "we haven't had any problems anywhere else." So I asked them to go check their transformer and meter. I haven't heard back yet. I know they are still extremely busy trying to fix the storm damage.
Thanks for all the assistance. I will keep you all updated on anything that arises out of this.
