In order to solve the problems of correctly identifying fault classes in fault diagnosis of analogue circuit and improve classification ability, a fault diagnosis method for analog circuits based on AdaBoost algorithm and hypersphere support vector machine (hypersphere SVM) is developed in this paper. This algorithm uses Hyper-sphere SVMs as weak learners of AdaBoost and use AdaBoost algorithm to...
Based on the experiment carried out in the lab on several cables in which there are some typical PD models, the relationship between the single acoustic signal generated by the partial discharge and the apparent discharge magnitude in a line frequency cycle are researched. Further more, through the detection system which is combined of the VHF PD detection method and the acoustic emission detection...
