Current “condition based maintenance decision making” of power transformers has not taken reliability and economy into consideration generally, which will cause large financial losses to electric enterprises. To solve this problem, a maintenance decision making model based on life cycle cost analysis was established to select the best maintenance strategy for transformers. After building the relationship...
Power transformer constitutes the core component of power system for energy transmission and distribution. The operation status of power transformer directly affects the security and stability of the power grid operation. Any faults of power transformer can result in significant economic losses. Monitoring and diagnosis provide an effective way to detect the potential fault. However, the traditional...
Furfural analysis is considered as a reliable method to estimate aging of cellulose insulation paper and is widely applied in assessing the condition of field transformers. However, the actual concentration of furfural in insulating oil is influenced by oil replacement, and the correction method is seldom studied. In this research, an accelerated thermal aging test of oil-paper samples was conducted...
