MEASURING APPARATUS FOR MEASURING TRANSMISSION LINE TEMPERATURE

A measuring device (10) for measuring a transmission line temperature, includes a temperature sensor part (200), a current transformer part (420) provided in a ring-shape surrounding a transmission line (100) to generate power from a magnetic field introduced around the transmission line by electromagnetic induction, a wireless communication part (600) to transmit temperature data of the transmission line measured by the temperature sensor part by the power from the current transformer part, a main body (300) to hold the current transformer part and the wireless communication part on an outer side of the transmission line, and a clamp (700) connected to one end of the main body to clamp the transmission line. The temperature sensor part (200) is provided on one side of the main body in an axial direction of the transmission line, on an opposite side from the clamp, so that the temperature sensor part is separated from the clamp.
