Abstract:
    This invention relates to a fault test system for quench-superconductor current limiters characterizing in including a commutation module, a logic circuit module, an A/D conversion module and a super control switch module. The advantages include: 1, combining hardware devices and computer soft programming, 2, applying di/dt fault current change rate to control the operation of the superconductor fault limiter, 3, cooperation of the A/D conversion module and logic circuit to increase the accuracy of the operation of the fault limiter, 4, utilizing the high speed data computation and process ability of computers to increase the reliability of said control system.
