EMI2.1
Transformators vom Rotor aus Strom im gleichen Sinne zugeführt, dann heben sich die Wirkungen der beiden Sekundärwicklungsteile auf jedem Transformatorkern auf, so dass eine Übertragung auf'die Primärwicklung unmöglich ist. Auch die Streuflüsse heben sich in ihrer Wirkung vollkommen auf, wenn sich die beiden Sekundärwicklungen jedes Kernes gut überdecken, oder wenn sie sich zur Primärwicklung in symmetrischer Lage befinden. Keineswegs darf bei dieser Schaltung etwa durch Verbindung der sekundären Phasenmitten ein Sternpunkt geschaffen werden, da dann eic ? Übfitrugung der Selbsterregerströme auf den Primärkreis wieder möglich wird.

EMI2.1
Transformer supplied by the rotor from current in the same sense, then the effects of the two secondary winding parts cancel each other out on each transformer core, so that a transfer to the primary winding is impossible. The effect of the leakage flux is also completely canceled if the two secondary windings of each core overlap well, or if they are in a symmetrical position to the primary winding. In no way may a star point be created in this circuit by connecting the secondary phase centers, since then eic? Transfer of the self-excitation currents to the primary circuit becomes possible again.
