Оптимизационное повышение чувствительности выявления дефектов в обмотках электрических машин как резонансных схемах

Abstract

The actuality of the problem and the principles of detecting the wire isolation defects are shown. The sensitivity of the methods of the electric machine windings control is defined. The methods of getting high sensitivity of detecting the defects are proposed. The optimization of time parameters of the testing signal is made and the optimizing selection of the section of the amplitude-to-frequency characteristic of the winding is performed.
