要約(日本語): Short-circuit inductance of the transformers is measured by using a frequency response analyzer (FRA). These values show that short-circuit inductance decreases along with the frequency.(1) There has a phenomenon that magnetic flux cannot penetrate an iron core at a high frequency region. To study this, we made current ratio measurement of a transformer at a high frequency region up to several 10s kHz and magnetic flux versus current measurement at the high frequency region. In this paper the results of former one will be reported.
