1. A compact high voltage transformer of the type having three coil assemblies each of which consists of a low voltage coil concentrically arranged around a core and a high voltage coil, the high voltage coil comprising:

  • a multisectional coil having five layers of wire in each of four coil sections, the high voltage coils being arranged in an electrical wye connection on a coil support with a last layer of one section being electrically connected with a first layer of another section, said four coil sections consisting of a first pair of coils connected in series and a second pair of coils connected in series, said first and second coil pairs being electrically connected in parallel;

    a top terminal connection proximate a top core yoke;

    a bottom terminal connection proximate a bottom core yoke; and

    a plurality of terminal connections intermediate the high voltage coil to provide electrical connection to each of said pairs of coil sections for providing reduced spacing between said high voltage coil and said low voltage coil and between said high voltage coil and said coil support and said top and bottom core yokes.
