Abstract:

Abstract: The transformer is an important part of the power supply system. From the technology parameter of transformer, on the basis of transformer equivalent circuit, the article researches the calculation of transformer short-circuit current, the characteristics of current when no-load pressure and no-load closing. The author analyzes the operating characteristics of transformer from many aspects.
