Abstract
A new method for analyzing inrush currents in transformers is conceived by modifying the finite element method. Using this method, the detailed behaviour of the transient flux can be analyzed taking into account the residual magnetism and three-dimensional leakage flux. The new method is especially effective in the calculation of the inrush currents of three-phase transformers. The inrush currents are examined experimentally by using a new method for measuring the residual magnetism and an equipment which controls switching angles.
