Wide band oil-immersed transformer considering the frequency-dependent parameters.

What is it about?

Accurate transfomer transmission line model is very important to calculate potential distribution. In this paper, the frequency-dependent characteristic of transformer winding is considered and a more accurate model based on fractional calculus is proposed.

Why is it important?

Traditional transformer model neglects fractional characteristic of oil-immersed windings . In this paper, we consider the key factor and propose a more accurate transformer based on fractional calculus.
