Abstract (en)
[origin: WO2011141038A1] The invention relates to a measuring method and a device that permit a better evaluation of bearing currents. Furthermore, a method and device are specified, said method implementing a non-contact measurement of bearing currents. A non-contact voltage measurement is performed by means of a series circuit of capacitors. The bearing voltage can be detected especially well in this manner even in the high frequency range.
