摘要：

We have investigated the resistance of current limiting elements in order to improve the working voltage. The element consisted of YBCO thin film on sapphire substrate and metal film on AIN substrate. The working voltage was improved by optimizing the resistance of metal film, and the high value of 83 V/cm was obtained. Furthermore, a module composed of 12-connected elements in series was assembled. The current limiting properties of this module were measured using a capacity discharge circuit. The short circuit current of 1.74 kA was reduced to 460 A, the voltage drop of was 5.45 kV peak, and the dissipated energy was 15 kJ. (C) 2002 Elsevier Science B.V. All rights reserved.
