  • Partial discharge experiment power supply system for extra-high voltage transformer and method thereof
    Patent number: 8890540
    Abstract: A partial discharge test power supply system for an extra high voltage transformer comprises: an electric motor (1); an intermediate frequency generator (2) driven by the electric motor and outputting an intermediate frequency voltage; a middle transformer (9) receiving the intermediate frequency voltage and outputting a test voltage to be applied to a test sample (11) by a generator outlet (5); a low-voltage compensating reactor (8) connected between the intermediate frequency generator and the middle transformer; a high-voltage compensating reactor (10) connected between the middle transformer and the sample; wherein the electric motor and the intermediate frequency generator are arranged in a metal housing (100).
