Circa 1975 there was an IEEE paper published outlining a novel way to perform short circuit calculations, called the MVA Method Of Fault Calculation(Exact title unknown).
Even though it was apparently not adopted by IEEE or Electrical Engineering Schools, it is an extremely simple system to use...
Anyone have a site that describes how a Transformer's Percent Impedance is measured either at the factory or in a lab?
I recall that it is done by short-circuiting the high voltage side and then increasing the low voltage side voltage until full rated current is reached in the high voltage...
