Abstract :
A new system for analyzing ac magnetostriction of electrical steel sheets, has been developed. This system has the following advantages: (a) AC magnetostriction waveforms can be precisely measured up to 4 kHz, and analyzed to harmonic components. (b) Non-sinusoidal flux density can be excited to simulate the distorted waveform in an actual transformer core
