Research on On-Line Detection Method of Transformer Winding Deformation Based on VFTO [PDF]
At present, the detection of transformer winding deformation faults is carried out in an offline state, which requires the transformer to cooperate with the implementation of planned power outages, or it takes place after the sudden failure of the ...

Winding vibration caused by Lorentz force in shunt reactor and its control strategy [PDF]
In each vibration source of shunt reactor, the winding vibration caused by Lorentz force should not be ignored. In this paper, the electromagnetic-mechanical coupling field simulation model was established based on the structure of disks and blocks of ...

Research on Online Detection Method of Transformer Winding Deformation Based on VFTO Characteristics
At present, most of the winding fault detections of transformers use offline methods, which require the entire line to be powered off or after the transformer has been shut down due to a serious fault, and they cannot detect the running status of the ...
