A transformed current sensing relay (k2) with reduced AC impedance of the operating coil is accomplished by adding a shorted secondary winding (14) to an otherwise conventional current sensing reed relay. The shorted secondary winding (14) is preferably implemented with a copper tube over the existing coil and inside the magnetic circuit. This transformed current sensing relay (k2) is particularly advantageous for the line current sensing function in switched network communications equipment such as high speed modems, where the transformed relay (k2) exhibits substantially lower impedance at high frequencies than the conventional current sensing relay. This transformed current sensing relay (k2) allows for the elimination of bypass capacitors and results in significant cost and space savings. Moreover, the tranformer nature of the tranformed current sensing relay (k2) allows for the elimination of suppression resistors from the interface resulting in additional cost and space savings.
