Based on Comprehensive Analysis of Electro-Acoustic Multidimensional Signal Transformer Discharge Pattern Recognition
According to the characteristics and disadvantages of partial discharge electrical analysis method, an electro-acoustic and ultrasound combination partial discharge pattern recognition method is proposed.Firstly, the transformer partial discharge test systems wiring diagram is given, and anti-jamming measures are described.Secondly, Electrical pulse signals time-domain and ultrasound signal statistical features have been extracted to build feature vectors, and then the features is input to BP neural network, the typical partial discharge pattern recognition has been derived.Lastly, the partial discharge analysis system software is developed, and experiments show that the analysis method is effective and software process is correct.
