Investigation of Steady-State Single-Phase Short Circuit Modes of Phase-Shifting Autotransformer with Hexagonal Scheme and Adjusting Autotransformer

Abstract

The purpose of this work is to study the steady-state modes of operation of proposed new device at single-phase short circuit of the load for different connection options of regulating autotransformer to hexagon circuit of main phase-shifting autotransformer. As the result of calculations, the values of voltages and currents vectors in all windings of both autotransformers were obtained for the case of load connection to the middle taps of regulating autotransformer windings.
