Claim of US Patent No. 10,342,107

1. An apparatus comprising:a cascaded transformer set comprising a plurality of transformers, each transformer having a primary and a secondary winding, and each transformer comprising three insulating gaps, wherein in the cascaded transformer set, the secondary winding of one transformer feeds the primary winding of an adjacent transformer; and
a voltage divider comprising a plurality of capacitors, each of equal value, and a plurality of resistors configured to evenly divide a voltage applied to the cascaded transformer set among the insulating gaps of the cascaded transformer set;
wherein the plurality of capacitors comprises a plurality of discs, wherein each capacitor of the plurality of capacitors is formed between two discs of the plurality of discs,
wherein the apparatus further comprises an oil medium surrounding the plurality of transformers and the plurality of discs, and
wherein the plurality of discs and plurality of transformers are arranged such that each of the plurality of transformers is positioned between two of the plurality of discs.
