    Abstract: In allusion to the fault monitoring problem of high voltage circuit breaker operating mechanism, this paper raised a kind of fault detection method for gas insulated switch (GIS) based on kernel principal component analysis (KPCA) and support vector machine (SVM). The KPCA algorithm was used to reduce dimension of eigenvalue of coil current waveform, which was input multi-classified SVM. The practical sample experiment verifies the correctness and reliability of the algorithm, and the discussion is proposed to calculate the optimal parameter.
    Key words: failure detection; characteristic classification; gas insulated switch (GIS); kernel principal component analysis (KPCA); support
vector machine (SVM)
