Definitions

  • the two partial windings 5 and 6 have the same winding direction and generally the same number of turns and are connected to one another with their ends 7 and 8 and 9 and 10 which are not consecutive on the iron core 1 and are therefore connected in parallel. These interconnected ends are led to connection points 11 and 12, to which a burden 13 is connected.
