| Abstract: | A reasonable transfomer model for analyzing the transient process of closing with load is proposed. At the same time, a new algorithm is put forward to explain the fault current and transient flux when secondary winding is broken down during closing with load. The residual flux in iron core is analyzed too. |

| Keywords: | transformer closing with load residual flux |
