This could be done by comparing and analyzing temp info and line current info together.
Using a current /voltage logger along with a data logger may allow this. Supco makes a reasonbly priced current/voltage logger. It's ac only which would reduce some of its usefulness but it still would make a great Christmas gift for the tech who has everything :
If I can convince my wife to buy one along with all the other toys I want for Christmas, look forward to a Durham's Extreme Data Logging video... but I'm gonna need all of you to help me decipher the data!
