Isolation design of a 14.4kV, 100kHz transformer with a high isolation voltage (115kV)

In this paper, the isolation design procedure of a 14.4kV output voltage, 100kHz transformer with an isolation voltage of 115kV using Litz wire is presented. For designing the isolation, a comprehensive design method based on an analytical maximum electrical field evaluation and an electrical field conform design is used. The resulting design is verified by long and short term partial discharge measurements on a prototype transformer.
