Abstract:

The objective of this research is to utilize the ultrasonic method to analyze the property of partial discharge (PD) which is generated by the generator and the winding of the insulation stator. Therefore, a PD measurement system is built on ultrasonic and virtual instruments. Three types of PD models (internal PD model, surface PD model and slot PD model) have been constructed. During the analysis of these experimental results, this research has identified three types of PD models that discharge ultrasonic signals. This analysis shows the different features of these PD types. Both the ultrasonic signal and the frequency have obvious differences. In addition, an experiment based on a large rotating machine has been done to analyze the ultrasonic noise. The result indicates that the ultrasonic noises can be wiped off by the application of filters and algorithms. The application of this system facilitates the detection of early signs of insulation failure, which is an effective method for diagnosis of insulation faults.
