Summary:A measuring device for measuring the alternating current (AC) loss of a high-temperature superconductor is disclosed. In accordance with an embodiment of the present invention, the device includes a pulse power supply unit, which outputs pulse power in a cycle, a lead wire, which is formed on both sides of the pulse power supply unit and applies the pulse power to a superconductor, a degaussing coil unit, which is connected to one side of the superconductor and cancels an inductive voltage, a shunt unit, which is serially connected between one side of the degaussing coil unit and one side of the pulse power supply unit, and a measurement unit, which is connected to both ends of the shunt unit and measures an electric current flowing through the superconductor.
