Abstract (en)

[origin: WO2011036007A1] The invention relates to a measuring transducer having an electrical transducer, wherein the electrical transducer is connected to an electrical earth by means of an earthing line. Ferroresonant oscillations inside the measuring transducer can be detected quickly and reliably by connecting a primary winding of a voltage transducer to the electrical earth via an earthing line and by using a sensor on the earthing line.
