    Abstract: A current transformer for alternating current with direct current components is proposed, consisting of at least one transformer core with a primary winding and at least one secondary winding to which a burden resistor is connected in parallel and terminates a secondary circuit with low resistance. The transformer core comprises a closed ring core with no air gap produced from a strip made of an amorphous ferromagnetic alloy that is practically free from magnetostriction and has permeability &mgr;
