Abstract

In this paper, the transient vibrations of transformer windings are studied with the aim of identifying the winding structural conditions. First, a mass-spring mathematical model is established to explore the inherent mechanical characteristics of windings, and the analytical solution of the transient vibrations is deduced from the model. Next, a diagnostic parameter referred to as material consistency coefficient (MCC) is derived from the vibration decay curve of the transient vibrations. During the experiment, the model was validated on a full size, 50 MVA, three phase power transformer. Free vibration test was performed to simulate the transient vibrations, and the effect of the winding clamping force on vibration was also studied to assess the winding clamping state. The preliminary study shows that the transient vibrations are closely connected with the mechanical state of transformer windings.
