Wicklung des Transformators 14 sowie auch zur primären des Transformators 15 geleitet. Die beiden Transformatoren sind so ausgebildet, dass die dann in der Sekundärwicklung des Trans- formators 15 entstehende Spannung genügt, um den automatischen Trennschalter sowie die Signallampe zu betätigen.
Es könnte übrigens auch diese Sekundärwicklung unterteilt sein, um zwei voneinander unabhängige Stromkreise zu bilden, von denen der eine die Alarm-und der andere die Ausschaltvorrichtungen speist.
Auch wäre es denkbar, dass diese Vorrichtungen unter Fortfall des zweiten Transformators 15 in einen Stromkreis eingeschaltet würden, der direkt durch die Sekundärwicklung des ersten Transformators gebildet wird.
PATENT ANSPRÜCHE :
1. Kontrollvorrichtung für Erdschutzleitungen bei Wechselstromanlagen, dadurch gekennzeichnet, dass die Sekundärwicklung eines an das Netz angeschlossenen Transformators einerseits mit der Erdleitung selbst und anderseits mit einer die Erdleitung schliessenden Hilfsleitung verbunden und ausserdem noch in einen Stromkreis eingeschaltet ist, der direkt oder indirekt Alarm-oder Ausschaltvorrichtungen zum Ansprechen bringt.

Winding of the transformer 14 and also to the primary of the transformer 15. The two transformers are designed in such a way that the voltage then produced in the secondary winding of the transformer 15 is sufficient to operate the automatic disconnector and the signal lamp.
Incidentally, this secondary winding could also be subdivided in order to form two independent circuits, one of which feeds the alarm and the other feeds the switch-off devices.
It would also be conceivable that these devices would be switched on, omitting the second transformer 15, in a circuit which is formed directly by the secondary winding of the first transformer.
PATENT CLAIMS:
1. Control device for earth protection lines in AC systems, characterized in that the secondary winding of a transformer connected to the network is connected on the one hand to the earth line itself and on the other hand to an auxiliary line closing the earth line and is also connected to a circuit that directly or indirectly alarms or Brings shutdown devices to respond.
