“…During the long-term operation of bushings in complex environment, due to the combined action of mechanical pressure, chemical corrosion, surface pollution, over-voltage, humidity and other factors for a long time, the insulation of equipment will continue to decline, which may eventually lead to insulation breakdown and transformer fault [1][2][3]. Therefore, it is helpful to reduce the probability of equipment accident and ensure the safe operation of equipment to find the internal defects of bushings as soon as possible, effectively and accurately diagnose its insulation state information, and formulate a scientific operation and maintenance plan for bushings [4][5].…”

The bushing is one of the most important components of power transformer, and it is very important to find the internal defects of bushings as soon as possible, effectively and accurately diagnose its insulation state information. In this paper, the active power loss of 500kV transformer bushings have been analyzed, and the insulation state evaluation method based on active power loss is proposed. To verify the feasibility of evaluation method, one abnormal 500kV transformer bushing was selected to analyze its insulation state. The result shows that this method can be used as a powerful complement to tarδ.
