Abstract: Introduction was made to the construction of short-circuit experiment platform for the superconducting fault current limiter and its work mode and principle. This paper gave the call process of the experimental data collected from the lower machine DSP to PC’s VB program.The short-circuit experiment of magnesium diboride superconducting fault current limiter was conducted under the conditions of liquid nitrogen.The experiment results show that the platform could correctly reflect the voltages at two sides of large current generator and the superconducting coil currents and effectively measure the temperature variation of the superconducting coil, to lay the foundation for the continuous experiment under the conditions of liquid nitrogen.
Key words: superconducting fault current limiter; short-circuit test; platform
