Transformer derating with full wave rectifier load

Abstract

Transformers are basically passive devices for transforming voltage and current. Transformer allows voltage levels to be changed throughout the electrical distribution system. Transformers were simply derated to compensate for nonlinear loads. For this project, nonlinear load are full wave rectifier, resistive load and DC motor load. In this project, the Schaffner is used to analyze harmonic in the transformer using full wave rectifier and loads. The project explained either the single phase transformer need derated or still applicable for the three load circuits.
