On the nonlinear distortion coefficient of three-phase symmetric transformers regulated by magnetic switching.
Abstract
The design of a three-phase symmetric transformer with magnetic switching (TRMK), providing a smooth amplitude voltage control, is described. The results of measuring the nonlinear distortion coefficient of symmetric ATRMK and TRMK controlled by magnetization are presented. Given the design features of three-phase symmetric ATRMK (TRMK), controlled by the yoke of which is made in the form of a closed polygon, almost does not distort the shape of the curve of the output voltage and current consumption.
