摘要
The trend towards higher line kVA ratings and the growing intermeshing of power systems is increasing the likelihood that distribution switchboards will be subjected to unacceptably high short-circuit currents. Reliable and economic protection against these surge currents is provided by the Is-Limiter. This fast-acting switching device detonates a small charge to open the main conductor, which is designed to carry high operating currents. The current commutates to a parallel fuse with high breaking capacity, which limits the short-circuit current during the first rise. Is-Limiters are being used successfully in more than 1500 substations all over the world.
