Abstract

Dissolved Gas Analysis (DGA) is used to determine the faults occurred in transformer oil by analyzing the gas evolved from it. This paper has presented the application of Fuzzy Logic system for dissolved gas analysis. DGA results were carried out and the possibility of improving the diagnosis with the aid of Fuzzy Logic system has been brought out. The results show that higher value of accuracy for predicted cases when compared to others. By combining various DGA techniques and interpreting classical DGA with Fuzzy Logic system approach, we have increased the predictability of the tool with the reduced time and maneuver.

用模糊逻辑系统解释变压器油中溶解气体分析
溶解气体分析法(DGA)是通过分析变压器油中析出的气体来判断变压器油是否发生故障的方法。本文介绍了模糊逻辑系统在溶解气体分析中的应用。通过对分析结果的分析,提出了模糊逻辑系统提高诊断精度的可能性。结果表明,与其他预测病例相比,预测病例的准确率更高。通过结合各种DGA技术,并用模糊逻辑系统方法解释经典的DGA,我们在减少时间和机动的同时提高了工具的可预测性。
