Abstract: The present invention relates to a method for determining a state of a capacitive voltage transformer which, on its primary side, comprises a capacitive voltage divider having a first capacitor and a second capacitor. The first capacitor has a high-voltage connection for connection to a high voltage and the second capacitor has a ground connection. A first resonant frequency is determined by way of a plurality of first short-circuit impedance measurements at different frequencies on a secondary side of the capacitive voltage transformer while the high-voltage connection is connected to earth. A second resonant frequency is determined by way of a plurality of second short-circuit impedance measurements at different frequencies on the secondary side of the capacitive voltage transformer while the high-voltage connection is open. A capacitance ratio of the capacitive voltage divider is determined on the basis of the first resonant frequency and the second resonant frequency.

Abstract: A method for producing a profiled bead made of a plastic, particularly of a polymer, on a piece, particularly on a window pane. In the method at least a partial portion of an edge region or lateral face region of a surface of the piece is brought into contact with a forming face. The plastic is deposited stuck to at least part of the periphery of a surface of the piece untouched by the forming face and the external dimensions of the profiled bead formed are also defined by the forming face. The forming face is pressed against the edge region or lateral face region of the fixed piece using a flat support, the shape of which can vary under the pressure of a fluid. This then gives a better matching of the forming face to the contour and to any dimensional discrepancies of the piece.
