Simulation and Experimental Verification on Vibration and Noise of Current Transformer

Vibration and noise in power equipment is an important factor affecting its normal operation. Through simulation by multi-physics field, the flux density in the core, the magneto-strictive force on the core and the noise caused by the magneto-strictive effect of the core are studied. Through numerical analysis and measurement experiments, the main causes of noise produced by the current transformer are found out.
