Corona Resistant

Polyimide Film High Frequency Testing and Applications

By

S. A. Filliben DuPont

Testing of corona resistant high performance Polyimide film insulation compared with inverter duty enamels under high frequency stresses. Different conductor geometries are discussed. The use of this insulation permits design changes that resulted in improved winding efficiencies. A brief history of successful designs using this film insulation for strand and or groundwall. Including a new rewind on a 69 MVA pump generator application for 13 kV stator coils.
