This paper mainly studies the magnetomechanical effects of three-phase three-leg
transformers with amorphous cores in different bending structures, where the magnetic …

A clear understanding of the vibration characteristics of power transformers is necessary to
detect electrical and mechanical faults in a transformer using vibration-based monitoring …

The vibration test of silicon steel, amorphous and nanocrystalline magnetic rings shows that
the magnetostriction of amorphous materials is much larger than that of silicon steel and …

This paper analyzes the phenomenon of vibrations in U-shaped (two-limb) inductors with
distributed air gaps due to both Maxwell and magnetostriction forces. A weak 2-D …

Medium-voltage, medium-frequency transformers (MFTs) are much smaller in size and
weight compared to conventional line frequency transformers. MFTs are very attractive for …

Recently, the relevance of audible noise of power transformers tends to increase due to the
growing environmental awareness. For sound assessment, two standardised methods …

Although the amorphous alloy core distribution transformers (AMDTs) have the advantage of
lower no-load losses over orientation silicon–steel distribution transformers, a high noise …

In this paper, a new model is proposed for Transformer-integrated Passive power filter
(TIPPF) to cancel the effects of not complete elimination of mutual-inductances and improve …

The total noise level of transformers is mainly influenced by harmonics in load current. The
reasons are the interaction of harmonics with large load current at power frequency and the …

Medium voltage, medium frequency transformers (MFTs) are much smaller in size and
weight compared to conventional low frequency transformers. The MFTs are very attractive …
