Abstract
A current sinking arrangement is provided that comprises a current sinking arrangement for connection to three phases of an AC grid, operable for reduction of short circuit fault currents in the AC grid, the current diverting arrangement comprising first, second and third phase arrangements, each including first and second grid terminals and a current diversion branch having a first impedance and a first switch and connected to a common floating conductor. On reception of a signal indicating a fault, which requires fault current reduction, a switching arrangement is arranged to make the first switches conducting so as to divert a portion of the fault current away from the AC grid fault location to the common floating conductor.
