  • Patent number: 10203363
    Abstract: The DC leakage current detector for detecting leakage current in a DC bus includes a pair of transformers each comprising a magnetic core and excitation and detection windings would about the magnetic core, with the magnetic core positionable about a pair of conductors that create a magnetic field that is a sum of currents in the conductors. An excitation and biasing circuit is connected to the excitation winding in each transformer to inject a current signal thereto that creates a changing magnetic flux in the core of each transformer and a detector output connected to the detection winding in each transformer to receive a voltage therefrom generated responsive to the magnetic flux in the core of each transformer, wherein the voltage on the detection windings provides a net voltage at the detector output whose value is indicative of a presence of a leakage current on the DC bus.

  • Patent number: 10197377
    Abstract: During operation of a capacitive proximity sensor that is provided with at least two measuring electrodes, a first capacitance measurement variable and a second capacitance measurement variable are detected. The first capacitance measurement variable is correlated with the capacitance of at least one of the measuring electrodes to earth, while the second capacitance measurement variable is correlated with the capacitance between at least one of the measuring electrodes and at least one further measuring electrode. A change in the first capacitance measurement variable is evaluated together with a synchronous signal profile of the second capacitance measurement variable in order to distinguish a proximity of a conductor coupled electrically to earth from the proximity of dielectric matter. In this manner, a body part passing into the detection space of the proximity sensor can be distinguished effectively from other substances and objects, particularly water.
