Simulation of a Voltage Transformer with a Magnetic Core Made of Amorphous Steels

The article presents the results of the development of a mathematical model of a voltage transformer with a magnetic conductor made of amorphous steels based on a system of nonlinear differential equations with an approximation of the steel magnetization curve by an analytical expression. The model was tested on various brands of amorphous alloys and provided for the evaluation of the validity of the statement about the influence of amorphous steels on the equipment antiresonance properties. A model of an antiresonance voltage transformer based on the finite element method and created with the help of a FEMM PC was created, which allowed obtaining a graphical representation of the distribution of magnetic induction in the magnetic core of a voltage transformer. The possibility of using these alloys in the design of the transformer magnetic circuit is evaluated.
