碩士 === 中原大學 === 電機工程研究所 === 90 === This thesis analyzes the saturation characters of amorphous core transformer and re-establish it’s hysteresis loops by field measurement. The hysteresis loops of silicon steel core transformer are also measured. Then the results are compared. We measure the different core transformers（single-phase, 6900/240 V, 25KVA） each by means of harmonic voltage generator and power quality recorder. In this experiment, the test voltages（RMS value） are chosen from 160V to 265V. We find the iron loss and hysteresis loss of amorphous core transformer are about one-third of silicon steel core transformer. However the copper loss is not much difference. We hope that the results can serve as useful reference for the designer and user of transformer.
