Abstract :
The aging process in transformer insulating oil was studied by measuring the leakage current in a ceramic sensor. The current of the sensor shows a close relationship with the acid value and the breakdown voltage of the transformer oil. The sensor has excellent physico-chemical properties, such as lack of chemical reaction with the oil and stable adsorption of conductive impurities. Therefore, the experimental data show good reproducibility
