Abstract
A stationary induction apparatus includes a core, a winding wound around the core such that the core serves as a central axis, and an annular electrostatic shield disposed adjacent to at least one of ends of the winding in a direction along the central axis. The electrostatic shield includes a conductor and a second insulating coating that coats the conductor. The electrostatic shield has a potential lower than a highest potential in the winding.
