Abstract
This paper presents a monitoring technique of pole transformers using AC bridge circuit. And to detect the capacitance in oil more effectively, this paper used AC bridge circuit. The sensor in oil which could be placed inside of the distribution transformer can measures the changes of capacitance in oil. And with the sensing of the upper part's capacitance, it is possible to determine the changes of the oil height. Establishment of the proposed system helps to build the confidence in monitoring of the pole transformers.
