Abstract :
The analysis of the composition of dissolved gas composition and concentration in transformer oil is the common method for transformer to performance evaluation and schedule fault type. This paper is based on sensor technology, a vice sensor is proposed to establish bridge sensor circuit to compensate for the traditional gathering of non-linear error, so as to improve the response characteristics of the sensor and the work performance. Then putting this system into field, and the analysis of test data showed that the system can perfectly reflect the insulation performance status of transformer.
