Construction and Application of Online Vibration Frequency Response Analysis Method for Converter Transformer Winding

High Voltage, EarlyView.
ABSTRACT The harmonic current and vibration of a converter transformer are effective pieces of information for detecting mechanical faults in the winding. In this paper, the ratio of vibration acceleration to the current squared is defined as the vibration frequency response function (VFRF) of the winding, and then, a novel online vibration frequency ...
