In-Service Power Transformer Life Time Prospects: Review and Prospects
نویسندگان
چکیده
Power transformers are essential assets in power system networks that must be meticulously monitored throughout their operational life cycle. Given a substantial percentage of in-service around the world have reached end projected technical lifespan, utilities adopting various transformer condition-based maintenance strategies to minimize potentially devastating equipment failure. Thus, further usage aging fleet can improved by gaining better understanding threatening factors. In-service and auxiliary components susceptible variety risks, which compromise performance efficiency, thus resulting failures, financial losses, outages. Hence, it is necessary investigate time issues so as fully grasp status order reduce failures operating costs. This paper presents unified framework attributes pertaining for operation evaluation together with summary recent findings explore current progress this rapidly progressing field. The failure statistics analysis presented first, followed an examination transformer’s insulation degradation mechanism. Furthermore, emphasis was on detailing commonly adopted models condition evaluation, fault diagnostics, remnant estimation. Despite significant advancements ascertaining health diagnosis prognosis technologies, including test accuracy, quick, precise localization, type classification, there still several shortcomings require additional research, future research perspectives also discussed.
