Abstract

Transformer vibration monitoring technique has been known to be safe, stable and resistant to interference. Based on the theories of transformer vibration and its origins, this study focuses on the equivalent mathematical model of transformer vibration, signal characteristics, as well as monitoring system for transformer vibration, to summarize research findings over recent years. A series of intelligent technologies have been adopted to reach certain diagnoses and monitoring outcomes; however, their applications are to some extent limited by the experience of users and other variants. The stability and reliability of techniques for monitoring transformer vibration need further improving.
