Advantages of Interwinding Capacitive Test Setup in FRA Diagnostics of Transformer Windings
Published by Wojciech SZOKA, Szymon BANASZAK, Konstanty M. GAWRYLCZYKZachodniopomorski Uniwersytet Technologiczny w Szczecinie, Katedra Elektrotechnologii i Diagnostyki, Poland Abstract. Transformers are the main element of the power system. Their reliable operation affects the efficiency of energy supply. Each transformer should be subjected to periodic diagnostic tests. Frequency response analysis (FRA) is a non-destructive diagnostic methodContinue reading “Advantages of Interwinding Capacitive Test Setup in FRA Diagnostics of Transformer Windings”
Autotransformers for Power Systems
Published by Waldemar ZIOMEK, PTI Manitoba Inc., Winnipeg, MB, Canada Abstract. When the primary and secondary voltages are obtained from the same winding, or from two windings which are galvanically connected, such a transformer is called an autotransformer. The paper will focus on fundamentals, design and applications of autotransformers of core-type design. The selected problemsContinue reading “Autotransformers for Power Systems”
