Abstract：Dissolved gas analysis (DGA) is the most approved method for transformer insulation state detection. Meanwhile, oil-gas separation technique plays a significant part in DGA. For oil-gas separation, membrane technique is considered as a novel and promising method. Compared with conventional methods, membrane technique possesses several merits, such as simple structure, small size and maintain-free. Therefore, it has become the focus in DGA field. A review of recent researches about polymers membranes applied in DGA was provided in this paper, which included research status of both the material and the structure of polymers membranes. Then, the characteristics of several typical polymers membranes were summarized for comparison. Lasty, based on current research results, the development trends of polymers membranes for DGA were proposed.
