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 ...
