Abstract
An improved transformer for withstanding and decoupling high voltage input impulses has a layer wound primary with interlayer insulation also serving as a spacer between the primary winding and the secondary winding and also as a spacer between the primary winding and the core. The secondary is preferably random wound on a preformed bobbin. A spaced adjacent relationship between the primary and secondary reduces the mutual inductance and interwinding capacitance.
