TY  - PAT
AB  - An electrical device comprising:first and second windings that are magnetically coupled such that, during normal operation, magnetic fields of the first and second windings interact and currents flow through the first and second windings; anda power controller arranged to control the current in the second winding in a fault situation, so as to reduce or limit the current magnitude flowing in the first winding or the second winding, or to synchronise the magnetic field of the second winding with the magnetic field of the first winding and thereby reduce their interaction;wherein the second winding incorporates a tap changer arrangement operable to reduce the number of turns in the second winding through which the current in the second winding flows, and thereby decrease the mutual inductance between the first and second windings and reduce the voltage magnitude required of the power controller in order to exercise control in the fault situation.Also provided is a method of operating such a device, and a tap changer arrangement that is well suited for use with such a device
