Automatically measuring the resistive loss of a transformer: A project in cooperation with Alstom Power Sweden
Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
In order to develop more economical and ecologically friendly transformers it is necessary to know the losses throughout the product development process. There are several losses related to transformers, but in this particular case the focus will be on the resistive loss of the transformer. In order to measure this loss first the resonant frequency of the transformer is determined. Since at resonance the secondary side of the transformer is considered to be purely resistive. The aim of this paper is to design and build a closed loop measurement system that is able to perform this task.
