FAULT CURRENT LIMITER

摘要

A fault current limiter of the type having at least one elongated core biased magnetically towards saturation by means of a surrounding magnetic field, and an AC coil surrounding the core, the fault current limiter including: an elongated core having a variable cross section along the axis of the core in the vicinity of the AC coil, providing increased saturation of the core and enhanced fault current limiting for a lower DC bias.
