PURPOSE:To equalize percentage impedances between high voltage and low voltage windings irrespective of tapping position in a transformer by separately winding divided tap windings in a symmetrical manner therebetween and alternatively inserting and connecting the separate tap windings at every one tap. CONSTITUTION:High voltage side tap winding 4a, low voltage side tap winding 1, high voltage side main winding 3, low voltage side winding 2 and high voltage side tap winding 4b are concentrically disposed sequentially from the inside around an iron core leg 5. The high voltage side tap winding 4 is divided into the windings 4a and 4b. As a result, either tap equally effect leakage magnetic flux distribution so as to equalize the percentage impedance between the high voltage and the low voltage windings. |
