Abstract
Aiming at four typical partial discharge pulse in transformer, the pattern spectrums of partial discharge signals are extracted by multi-scale open operation of mathematical morphology,from this it is observed that each type of discharge possesses its own pattern characteristics. Correlation analysis of pattern characteristics of each discharge type, in order to remove the redundant features and optimize the pattern characteristics.The experiment results show that the applications of optimized features enable to detect a good recognition rate and reduce the complexity of the recognition system.关键词
