Pattern recognition of partial discharge on generator stators by using model bars

Partial discharge (PD) can indicate defects in insulation of generator stator windings. In this paper, some generator model bars were made and some typical PD phenomena in generator stator windings were simulated. PD tests were also tried to find the features of composite PD. The data obtained from...

Summary:Partial discharge (PD) can indicate defects in insulation of generator stator windings. In this paper, some generator model bars were made and some typical PD phenomena in generator stator windings were simulated. PD tests were also tried to find the features of composite PD. The data obtained from the test were analyzed and the spectrums of different types of PD were plotted using statistical parameters to reveal the feature of different patterns of PD. A BP neural network was also used to recognize the PD patterns.
