| Abstract: | This paper discusses the sources, spreading paths and characteristics of noises under the condition of on-line detecting partial discharge (PD) in transformers. On this baSis, an antiinterference measuring circuit using the method of pulse polarity discrimination is developed. The analysis and tests show that the operation of this circuit is not affected by the difference of phase and amplitude between two input signals. Correct and stable signals of PD of transformers can be provided by the use of this circuit. |
