Abstract

An electrical component is suggested. The component comprises: a ferromagnetic core (10) with a first and a second leg (11, 12); a primary winding (20) with a first primary winding portion (21) arranged around the first leg (11) of the ferromagnetic core and a second primary winding portion (22) arranged around the second leg (12) of the ferromagnetic core; wherein the first primary winding portion (21) and the second primary winding portion (22) each comprise a plurality of parallel connectable conductors (1, 2, 3, 4, 5, 6) arranged around the ferromagnetic core in a cross section with the conductors being radially displaced with respect to each other at radial row positions, wherein the number of conductors (1, 2, 3, 4, 5, 6) of the first primary winding portion (21) is equal the number of conductors (1, 2, 3, 4, 5, 6) of the second primary winding portion (22) and each of the conductors (1, 2, 3, 4, 5, 6) of the first primary winding portion (21) is connected in series with one corresponding conductor (1, 2, 3, 4, 5, 6) of the second primary winding portion (22), whereby a conductor (1, 2, 3, 4, 5, 6) of a radially outer row of the first primary winding portion (21) is connected in series with a conductor (1, 2, 3, 4, 5, 6) of a radially inner row of the second primary winding portion (22), thereby reducing the sum of the magnetic flux between parallel connectable conductors (1, 2, 3, 4, 5, 6) of the first and second primary winding portions (21, 22).
