Study of effective methods of characterisation of magnetostriction and its fundamental effect on transformer core noise

Magnetostriction of core laminations is one of the main sources of transformer acoustic noise. The magnetostriction of grain oriented silicon steel is extremely sensitive to applied compressive stress. A measurement system using piezoelectric accelerometers has been designed and built. This was opti...
