| Abstract: | The paper discusses the form of moisture in power transformers oil and its harm, and analyzes the working principle of capacitive humidity sensing element by using polymer material, polyimide film. It adopts an on-line monitoring of moisture in power transformer oil. The results show that using the moisture transformers for power transformer oil is consistent with the national standard test methods, Karl Fischer reagent method. It ensures the safe operation of the power transformer through online monitoring of moisture in power transformer oil. |
