Hi John,Certainly. The measurements work for any transformer. The limiting factors are the measurement equipment. Primary short circuit current is really the measurement where we are often limited (at least accurately). Thus, pole transformers and xfrm's of of similar power are difficult. Even my test MOT was at the end of my capability (but I was happy I could take it up to at least it's rated voltage). NST's are very easy as their low current.
My 12/60 has 1/2 the shunts removed bringing it up to 12/200 or so. Although I did the measurements with this transformer, I think it would be good to simply go after an off the shelf unit for at least the purpose of looking at Cres. I expect C to be lower than a standard impedance calculation at low input voltages. At rated input, I expect it will be near, but I and others often run a variac and push it up to 140V input. This will likely move C up, but also, k rolls off steep at high input voltages, so it will be interesting to see how that area of input performs and is really the input range I'm most interested in.

Hi Bart, 15/30 eh? Would these measurements (X2) work for the 15/60? Joe
