"I have a Simpson volt-watt meter here I'm thinking about getting
calibrated."
Perhaps you could get one of your larger variacs and put in a smaller fast
blow line fuse, then slowly bring up the voltage on some kind of a load.
Keep taking readings until the fuse blows. Wouldn't the fuse rating times
the input voltage on the variac be your relative watt reading?
OR: put the fuse on the load side and do output calculations if you think
that would be more accurate.
