In recent years, many of the researchers in the field of the discharge-aided environment improvement technology have been published, and it is expected that such a tendency will be continued for a considerable length of time in the future, and many fruitful outcomes are anticipated. It has conventionally been believed that that the understanding of the uses of discharge phenomena has mostly been due...
The purpose of this research was to predict breakdown of electrical equipment due to deterioration of insulation. An internal discharge pulse measurement system which could analyze the distribution of the discharge according to each phase area of the applied voltage (AC 50Hz) was developed. The system's features were as follows. A half cycle of the applied voltage starting from the negative peak and...
Many kinds of new polymeric materials are now used as insulation for power cable and other electric apparatus. Thus, the requirements for these materials are becoming more severe as the usage of such materials becomes more widespread.
In recent years, gas insulated apparatus has been widely employed in power engineering. In future, the application of SF6 for the GIS may be implemented to gas cables as well as in the other electrical apparatus. Thus, it is considered that the development of simple methods for the detection of gaseous components can be important, from the view point of the maintenance and of the usage of gas mixtures.
