Abstract: For energizing the rotating field winding of electric machines without mechanical contact, the contactless energy transfer (CET) with a rotary transformer (RT) and a power converter is a ...

What’s driving a fundamental shift in engineering, procurement, and construction (EPC) contracting? Equipment lead times.

Abstract: In the case of the modern inductive current transformers the most important factor that have influence on their wideband accuracy is the self-distortion of the secondary current caused by ...
