Abstract

PURPOSE:To prevent the change of tertiary voltage according to the position of a tap by winding tertiary winding on a core, on which exciting winding to which constant voltage is applied is wound. CONSTITUTION:The tertiary winding 3 and the exciting winding 5 are wound concentrically on a main leg 74. When medium-voltage terminal voltage (voltage between u and v) is made constant and high-tension terminal voltage (voltage between U and v) is varied, the excitation of the core leg on which the winding 5 is wound does not change according to the position of the tap because voltage between both terminals u, v of the winding 5 is constant. Accordingly, the voltage of the winding 3 is also constant without depending upon the position of the tap.
