In order for the coupling to not have changed as a function of 
sqrt(1-(Ioc/Isc)), then Isc measurement would be where error is 
introduced. As the waveform becomes less sinusoidal, possibly there is 
error, but the error would have to be very high (2.4A at the 150V 
setting). I would expect coupling to change in NST's due to the 
effectiveness and change of current into the shunts as voltage is increased.

Maybe I should run the test again with a CT and scope as opposed to true 
rms meter?

Take care,
Bart
