Condition monitoring and fault diagnosis of power transformer using vibration analysis method has attracted great attention. This paper presents a transformer vibration model under short-circuit condition, which consists of two sub-models. One is a vibration model of internal windings, and the other is a signal transmission model. In the laboratory tests, the parameters in the model is measured using...
The mechanical faults of a transformer are predicted with monitoring its vibration, which is a new technology put forward recently for condition based monitoring of transformers. The key technology of vibration method is how to identify the effective features of the vibration signal. Here, a new self-adapting time-frequency analysis method - local wave method which is developed from the empirical...
