"NSTs
are current limited and the current usually isn´t very high (which
doesn´t mean it isn´t deadly), so paralleling NSTs might not be a
true problem in the real world (esp. since coil(er) run times are
pretty low and NSTs are designed for a 24hr/day/year operating
period). However, paralleling a PT or a pole pig, will probably
lead to the problems mentioned above, unless they are of the
exact same type.

	Well stated.  Pole pigs have very low internal impedance, so the
current flow would be the difference in voltage divided by the sum ot
the internal reactance of the two transformers.  In commercial practice
"equalizing inductors" are sometimes used when paralleling transformers,
at the expense of increased total reactance and poorer line regulation.
