| Abstract: | The paper expounds the mechanism of insulator contamination flashover and the relationship between its running status and leak current. Combining the factors of temperature and humidity, the running status of insulators is estimated based on the amplitude and statistic number of pulse current in different phases. And it is concerned with an on-line monitoring system by using SMS to send parameters of insulators. The results show that the project has the characteristic of simple structure, easy operating and reliable measurement. |
