Provided is a calculation method for transformer primary coil induced electromotive force. The method comprises the following steps: a transformer no-load vector diagram is established and a corresponding transformer equivalent circuit is obtained according to transformer no-load current (img file='130849...
After reaching the maximum steady-state flux, the core becomes saturated, and producing more flux requires a lot of current. This high peakcurrentdrawn by the transformer primary is calledtransformer inrush current or magnetizing inrush current. Magnetizing inrush current in transformer is the curren...
