Abstract

The distribution of the magnetic flux in the zone of rod contacts is investigated using the model of transformer cores. The effect of the anisotropy of magnetic characteristics of steel on magnetic losses and the transformer building factor is demonstrated. A method for estimation and forecasting of the building factor value is proposed. The investigation was performed using anisotropic electric steel of the 3408–3409 grades manufactured at OOO VIZ-STAL’.
