Abstract: When a disconnecting switch in a gas insulated switchgear (GIS) operates, a high frequency oscillating surge called very fast transient (VFT) is generated. The VFT may set off overvoltage in ...

Abstract: Transformers often encounter electromagnetic transients, such as ferromagnetic resonance and inrush currents. An accurate low-frequency modeling of transformers is essential for analyzing ...

The core provides a path for magnetic flux and is typically constructed from high-permeability silicon steel to minimize losses. Laminating the core into thin sheets reduces eddy current loss and ...

Transformer core design uses laminated silicon steel or ferrite to guide magnetic flux, reduce hysteresis and eddy-current losses, control permeability and saturation, and optimize inductance in power ...
