A coil of an embodiment is formed by winding a winding conductor in which a conductive conductor is molded by a resin, wherein the winding conductor has the resin filled to a surface of the conductor without leaving any spaces.

Coil and method for manufacturing coil

A molded stationary induction apparatus is provided with: a winding the surface of which is covered with resin or an insulating material containing resin; a closed vessel in which the winding is housed and air having pressure exceeding atmospheric pressure is sealed; and a heat exchanger which cools the air in the closed vessel.

An optical voltage transformer is connected with an external electric device and includes a primary electrode to which a measured voltage is applied by the external electric device, a first secondary electrode provided oppositely to the primary electrode, an insulation layer provided between the primary and first secondary electrodes and constituting an insulation cylinder integrally formed with the primary and first secondary electrodes, a ground layer provided on an outer circumference of the insulation cylinder and around the first secondary electrode for securing a capacitance by interposing the insulation layer between the ground layer and the first secondary electrode, and an electro-optic element for measuring a voltage between the first secondary electrode and the ground layer. According to the optical voltage transformer, measurement of the measured voltage can be done with high accuracy without affected by its surrounding environment and its downsizing can be achieved by reducing the number of its components.
