The article presents the results of studying the influence of amorphous steels on the antiresonance properties of voltage transformers. The authors developed a mathematical model of a voltage transformer with a magnetic circuit using amorphous steels based on the system of nonlinear differential equations with approximation of the magnetization curve of steel by a hyperbolic expression. The model was applied to the calculation of a voltage transformer with different brands of amorphous alloys. The model of the anti-resonance voltage transformer based on the finite element method and created with the help of the FEMM PC was used to verify the obtained results which made it possible to obtain a graphical representation of magnetic induction distribution in the voltage transformer magnetic circuit.
