Abstract

In this paper is presented a low cost automated measurement system developed to obtain the core losses and the excitation current of single-phase transformers. This system includes specifics hardware and software that allows the accomplishment of this aim, as specified by the user. Due to the techniques used in the acquisition and computation of the waveforms involved in loss calculation, the core losses and excitation current are obtained with high accuracy.
