Study on the Relationship between Total Hydrocarbon and Gases Dissolved in Transformer Oil

Abstract:

Dissolved gas analysis (DGA) in transformer oil is considered as one of the preferred projects to discover the potential faults of the transformer. To identify the aging characteristics of oil-immersed transformer oil in long-term operations, it is important to study relationship between total hydrocarbon and gases dissolved in transformer oil. This paper used Pearson correlation coefficient to analyze the relationship with the data of DGA. At last, it gives the result that the correlations between the total hydrocarbon and carbon monoxide, methane, ethane, ethylene, acetylene was positive. Therefore, this study lays the foundation which help to diagnose the aging status of transformer.
