  • Method and apparatus for performing a surge test of electrical insulation
    Patent number: 12704551
    Abstract: A method of operation and apparatus is provided for performing a surge test of electrical insulation of at least part of a winding under test, the winding being a winding of an electrical machine. The apparatus comprises a test device having a surge generator, at least two test connections for connecting to the test device, and a damping device comprising a resistance. The damping device is connected across the part of the winding under test, the test connections are arranged to connect a parallel combination of the damping device and the part of the winding under test to the test device and a voltage impulse is generated using the surge generator.
