Traction engines turn-to-turn armature coil insulation testing process using the method of wave response readout

The article deals with the suitability of wave response method aptitude for traction engines turn-to-turn armature coil insulation testing and development of testing coil adequate model for further researching of physical processes occurring while testing. The method of wave response readout in armature coil reported is described in the article. The equivalent circuit of armature coil relating to wave response method is given. The wave responses got during physical model testing, simulating in MATLAB are shown. The real and simulating results analysis allows you to approve the proposed equivalent circuit adequacy. This equivalent circuit may be used for simulating of traction engines insulation fails relating to wave response method.
