Fault current limiters (FCL) are extensively needed to suppress fault currents, particularly for trunk power systems heavily connected to high‐voltage transmission lines, such as the 500‐kV‐class power system which constitutes the nucleus of the electric power system. In this paper, we propose a new FCL system, consisting of solid‐state diodes, a dc coil, and a bypass ac coil, and describe the specifications of the trunk electric power system and the 6.6‐kV reduction model. Also we propose a 6.6‐kV trial model and describe an efficiency test with a short circuit generator, which we have trial produced for the new FCL system. © 2001 Scripta Technica, Electr Eng Jpn, 137(3): 29–36, 2001
