abstract
A major part of the transformer noise and vibrations comes from the deformation of the magnetoelastic material of the transformer core. In this work the vibrations of a test transformer core are measured by means of a laser scanning vibrometer. Due to the presence of the higher harmonics in the grid voltage, in addition to a purely sinusoidal magnetisation of the core the presence of a third harmonic is also studied. The vibrations of three points along the core leg are measured. Moreover, for a better illustration of the deformation a 3-dimensional surface scan of the core leg is also performed. The results show that the core deforms more in the corners than in the middle of the leg. The influence of the third harmonic of the magnetisation on the core deformation is also more significant in the corners of the leg. The core deformation shape under a sinusoidal magnetisation with a higher harmonic is more wavy and fluctuating than that under a purely sinusoidal magnetisation.
