PATENT-ANSPRUCH: Mehrphasiger Transformator oder Drosselspule mit geerdetem Nullpunkt und einer oder mehreren überzähigen Säulen, dadurch gekennzeichnet, dass der Nullpunkt über Wick- lungen geerdet ist, welche mit dem magnetischen Kreis der überzähligen Säulen verkettot sind. PATENT CLAIM: Multi-phase transformer or choke coil with earthed zero point and one or more superfluous columns, characterized in that the zero point is earthed via windings which are linked to the magnetic circuit of the superfluous columns.
