A simple and rather effective power line monitor:  get an old cheap laptop with some sort of sound input capabilities with at least a semi-usable battery,  an AC output wall wart,  and a couple of divider resistors.   Record the AC line as audio during your experiments.   You can analyze the audio in real time or after the fact.   I have seen software packages that are geared specifically to audio power line monitoring,  but don't remember what they are.
