Study on Transformer Silicon Steel Magnetic of Different Joint Forms

Abstract:

The operation characteristic of transformer when DC bias phenomenon occurred was detected by Epstein frame. Results with different methods of joint forms are obtained in this paper. The circuit structure and measuring principle were analyzed in detail. Average magnetizing curve, magnetic hysteresis loop and loss curve with joint forms method of full tap and 30°,60° tap were obtained. The theoretical basis and experimental evidence for improving the capacity on restraining DC bias during designing transformer are provided.
