Description

Einrichtung zur Messung hoher Spannungen, Im Hauptpatent ist eine Einrichtung zur Messung hoher Spannungen mittels Vorschaltkondensators beschrieben, bei welcher der Meßstromkreis eine Induktivität enthält, durch die der parallel zum Meßstromkreis abfließende Kapazitätsstrom ganz oder zum größten Teil kompensiert wird. Die dazu erforderliche Induktivität kann erfindungsgemäß ganz oder teilweise durch den Magnetisierungsstrom eines im Meßstromkreis befindlichen Meßwandlers bedingt sein, so daß keine besonderen Drosselspulen oder nur solche von geringer Größe notwendig sind. , -Wenn der Magnetisierungsstrom eines ohnehin vorhandenen Meßwandlers an sich nicht zur Kompensation des Kapazitätsstromes ausreicht, kann er erfindungsgemäß künstlich vergrößert werden, beispielsweise indem der Eisenkreis des Meßwandlers einen Luftspalt erhält. Die notwendige Induktivität wird auf diese Art billiger hergestellt als durch besondere Drosselspulen.Device for measuring high voltages, in the main patent is one Device for measuring high voltages using a series capacitor described, in which the measuring circuit contains an inductance through which the parallel The capacitance current flowing to the measuring circuit is completely or largely compensated will. According to the invention, the inductance required for this can be wholly or partially caused by the magnetizing current of a measuring transducer located in the measuring circuit so that no special choke coils or only those of small size are necessary are. , -When the magnetizing current of an already existing transducer is on is not sufficient to compensate for the capacitance current, it can according to the invention can be artificially enlarged, for example by adding the iron circle of the transducer receives an air gap. The necessary inductance is cheaper in this way manufactured as by special choke coils.
