Abstract:
1. A sensor attached IC tag application high voltage equipment, comprising: a container filled with an insulating gas; a high voltage unit provided inside the container; and a sensor attached IC tag detachably mounted to a position where a sensor of the sensor attached IC tag senses a characteristic of a detection target of the high voltage unit, wherein the sensor attached IC tag is configured to communicate with an IC tag reader located outside the sensor attached IC tag application high voltage equipment, wherein the sensor attached IC tag is covered with a semiconductor material separate from the sensor attached IC tag having an electric time constant in which an inverse number of the electric time constant is larger than 1 MHz and the inverse number of the electric time constant is smaller than a communication frequency of the sensor attached IC tag such that the sensor attached IC tag communicates through the semiconductor material, and the semiconductor material protects the sensor attached IC tag from electrical discharges generated by the high voltage unit and electrical discharges occurring near the sensor attached IC tag.
