Just a comment for anyone who wants to log line voltage v. time. If you have an APC "Smart UPS" battery backup unit these will log voltage and frequency to a file. The unit connects to a computer via USB (and an AC power cable).
You can collect data over a wide area using these power supplies, logging data can be pushed over a network. I would not buy an UPS just to log power statistics but many people already have these So you might wonder what is the line voltage in your lab. If you have computer "server" of some kind you might also have an UPS and then you might already have logs of voltage and frequency going back for years.
