Elimination of transformer inrush currents by controlled switching. I. Theoretical considerations.

Elimination of transformer inrush currents by controlled switching. I. Theoretical considerations.

Transformer inrush currents are high-magnitude, harmonic-rich currents generated when transformer cores are driven into saturation during energization. These currents have undesirable effects, including potential damage or loss-of-life to the transformer, protective relay misoperation, and reduced p...
