Abstract
Since transformers are one of the most important and most used equipment in power network, investigating the factors which affect the loss of these equipments is of particular importance. Nowadays Amorphous metal core transformers have a significant place in today power market, since they exhibit 60-70% lower no-load losses compared to the Silicon crystalline steel core transformers. In order to enhance the design and cost and also to shorten the time to produce Amorphous metal core transformers, numerical analysis of the no-load as well as load conditions are of paramount importance and hence should be considered. On the other hand, temperature is one of the important and effective factors in transformer life, because increasing the transformer temperature leads to reduction of its rated life. In this paper, a 100 KVA unit transformer has been simulated by coupling ANSYS Maxwell and ANSYS FLUENT softwares and no-load and load losses are investigated. The results show that amorphous core transformer compared to Silicon Crystalline Steel core transformer reduce no-load losses about 65 percent. Furthermore, thermal analysis shows amorphous core transformer has lower temperature compared to the Silicon core transformer in no-load conditions.
