Abstract: A transformer (10) includes a ferromagnetic core (14); winding structure (12) mounted on the core; electrical terminals (40, 40′) connected to the winding structure; a fast transient mitigator circuit (52) including an impedance circuit serially connected between one of the terminals and the winding structure, and a capacitor connected from the one terminal to external ground. The mitigator circuit is constructed and arranged to reduce a frequency spectrum and magnitude of fast transients. An encasement (16), of an insulating resin, commonly encapsulates the core, the winding structure and at least the impedance circuit of the mitigator circuit.

Abstract: The invention relates to a device for measuring the direct component of alternating current, applicable in current measuring systems where a low direct component of alternating current and a high amplitude of the alternating component of alternating current occur. The device for measuring the direct component of alternating current comprises a current-carrying wire (1) around which there is located a magnetic core (2) provided with a gap (3) in which a magnetic field sensor (4) with insulated terminals (5) is located and it comprises a shorted compensating winding (6) or (9) which is made in the form of a single turn coil placed on the core (2).
