Interleaved—turn high-voltage transformer windings have found uses in many types of transformers withe different ratings. However, it is discovered that the most-commonly-used forms of interleaved windings have an unexpected large internal oscillatory response to choppedwave or step wave impulse voltage. This paper studies this problem. The equivalent mathematical model for twin interleaved is given. This paper reports the characteristics of internal oscillation, and the distributions of voltage and current sinusoidal resonant component along the conductor have been deduced. This paper diseusses as well the reason for causing the oscillation and the method of reducing the oscillation.
