Since you have two of them, run them back to back (120 V stepped up to 12 
KV, then 12 KV stepped back down to 120 V).  Apply a large load (maybe your 
electric oven?).  You can then check the heat rise as mentioned above, or 
measure the voltage drop at the load compared to the input voltage.  This 
will give you an indication of the loss / power being dissipated in the 
transformer.
