Experimental simulation analysis for single phase transformer tests
Bulletin of Electrical Engineering and Informatics, 2020 Transformer is one of main components in electrical power system which role to increase or reduce voltage. Characteristics of transformer would be vital to ensure the voltage is fully transferred. A single-phase transformer is a type of power transformer that utilizes single-phase alternating current, meaning the transformer relies on a voltage cycle ...

Control of the Transformer Phase Powers Using a Single-Phase Voltage Source
Energies, 2021 Power flow in three-phase distribution grids containing single-phase prosumer voltage sources strongly depends on the RMS value of the voltage of these sources and their phase shifts in relation to the grid voltage.

Fabrication and experimental analysis of multiple-winding transformers for multiphase supply
Measurement + Control, 2020 This paper aims to fabricate multiple-winding transformers for polyphase supply that means more than the classical three-phase supply. Usually, transformers do not change the phase, that is, from single phase to three phase or vice versa, but according ...
