摘要： PURPOSE:To enable the detection of a partial discharge accurately and at a higher speed without being affected by any noise by a method wherein a frequency data with limited noises is taught to a neural network, features are extracted in a frequency characteristic data thereof when a partial discharge is detected and the features are inputted to the neural network to judge the generation of at least the partial discharge. CONSTITUTION:When a frequency characteristic data of a partial discharge to be outputted from a partial discharge detector 9 is detected, the extraction of features thereof and standardization thereof are performed. A frequency area with limited noises is selected from the frequency characteristic data subjected to the extraction of features and standardization to be turned to a pattern and the resulting data is inputted into a neural network device 20. The device 20 judges the generation of any partial discharge based on the frequency characteristic data patternized and the frequency characteristic data learned. This enables the detection of a partial discharge generated in an insulation equipment accurately and at a higher speed without being affected by noises.

摘要： PURPOSE:To enable automatic detection of not only known partial discharge but also unknown partial discharge with high accuracy and high speed by using neural network from features of a frequency characteristic data and a phase characteristic data of a partial discharge waveform. CONSTITUTION:Partial discharge waveforms generated in a gas insulated device are detected 7 and 12 and features of a frequency characteristic data and features of a phase characteristic data are extracted 13 and 14 from the waveforms. The features of the characteristic data of a frequency and phase extracted are compared with the characteristic data of the frequency and the phase learned to judge 15 whether the waveform occurs at a higher speed and with high accuracy. A neural network 15 can judge the waveform of the know partial discharge and moreover, the unknown partial discharge at a higher speed and with high accuracy. This judgment enables the obtaining of the results of judgemet automatically without the generation of any mistake by an expert. This also allows not only partial judgment but also the analyzing of a factor for generating the partial discharge and the results thereof can be outputted 15 to display.
