Evaluation Method and System Integration of Insulation Condition of Transformer High-voltage Bushing for Online Monitoring

Abstract

As one of the key components in the design and application of transformers, the insulation performance of transformer bushings directly affects the safe and stable operation of the power system. Due to the long-term influence of multiple factors such as electrical stress, load fluctuations, and environmental conditions on transformer bushings, their actual application performance is likely to gradually deteriorate, and there is a potential risk of failure during system operation. Therefore, based on the research results of the application of online monitoring technology for the insulation performance of power plant transformer bushings in recent years, the principle and corresponding method schemes of online monitoring for the insulation performance of power plant transformer bushings have been clarified. Combined with practical cases, the application effects of software and hardware have been verified, thereby providing technical support for the management of power systems in the new era.
