Application of RBFN using LPC of PD pulse shapes for Discriminating among Multi PD sources

초록

Partial discharge pulse shapes from variable PD(partial discharges) sources sustain many characteristics on them such as kinds of PD. Ultra high frequency antenna has wide bandwidth from 30kHz to 2GHz. Therefore, signals taken from UHF antenna have important attributes(rising time, falling time, shape factor and etc.) for electromagnetic sources, such as PD sources. We investigated PD pulse shapes from several PD sources using UHF antenna and the results were used for classification of PD sources. Features for discrimination are extracted from frequency distribution and LPC(Linear Prediction Coefficient) of time signal. RBFN are used for investigating the possibility of classification of multi-PD sources
