Abstract

A new concept for a compact, gas-insulated power transformer employing sheet wound aluminum coils with polymeric film insulation and, separate sealed cooling system is described. A design comparison is given to illustrate the potential benefits it offers in terms of lighter weight, smaller dimensions, higher efficiency, and less audible noise than a conventional transformer with an oil/cellulose insulation system. The technological challenges which must be overcome before this concept can be implemented are outlined in the paper and progress which has been made toward development of a complete design practice is discussed.
