Transformer design concept to increase the dielectric breakdown strength

By application of the physical laws of dielectrics we have shown that critical voltage stress areas of a transformer coil can be treated in such a manner as to minimize these stresses without the necessity of special winding configurations or overdesigning which result in more costly coils. They do however, require a thorough engineering analysis of the stresses and the dielectric constants of the insulating materials. It should be noted that both stress reduction techniques have been successfully applied to transformer designs for more than two years and are covered by the following United States Patents-3713061 and 3748616.
