Yes, this has been looked into several times. The point is that it is not a
significant problem on standard TCs, but on some magnifiers and valve TCs it
can become a potential mechanism for losses to occur.

The problem only manifests itself when the coupling between the pri and sec
is high, and when the average power developed in the pri is also high.
