Abstract
An object of the present invention is to provide a stationary induction electric apparatus that can improve insulating performance with a few additional structures. In the stationary induction electric apparatus comprising: an iron core; a low-voltage coil conductorwound on the iron core; an insulatorenclosing the low-voltage coil conductor; and a high-voltage coil conductorwhich is wound on the insulator and to which a voltage is applied from the outside, a first shield conductorwound adjacent to the inner peripheral surface of the insulator, a second shield conductorwound adjacent to the outer peripheral surface of the insulator, one end of the first shield conductor, and one end of the second shield conductor are electrically connected to any region of the high-voltage coil conductor.
