Abstract:
A stationary induction apparatus has: a winding to which AC current is supplied; an electrostatic shield which includes an electrostatic shield member having a hollow and an electrically conductive film wound around the electrostatic shield member, and which is configured to suppress the electric field of the winding; a housing which contains the winding, the electrostatic shield and the insulating fluid; an IC tag which has a sensor arranged in the hollow of the electrostatic shield member and configured to detect position of the electrostatic shield member, and a transmitter unit configured to transmit, by radio, information acquired by the sensor as a high-frequency signal having a frequency much higher than the frequency of the AC current; and a receiver unit which is arranged in the housing, receives the high-frequency signal transmitted by radio from the IC tag and transmits, by wire, the signal outside the housing.
