Current limiting arrangement for limiting current in electrical power system has circuit-changing member that reverses direction of residual magnetic field in first portion relative to magnetic field generated in first flux-circuit

摘要

A second winding (12) surrounds a second flux-circuit (14) connected in series with a first winding (11). A circuit-changing member (17) reverses the direction of a residual magnetic field in a first portion (15) relative to the magnetic field generated in the first flux-circuit (13) by the current in the first winding part (11). The reversal takes place between the first current limiting effort and a second subsequent current limiting effort. Independent claims are included for: (a) an electrical power system (b) a method of using a current limiting arrangement
