The method includes measuring a three-phase voltage, forming a discrete model for a periodic signal, the discrete model including the three-phase voltage and a difference between positive and negative voltage components of the three-phase voltage, forming a discrete detector based on the discrete model, detecting a fundamental wave component of the voltage and the difference between the positive and negative voltage components of the three-phase voltage from an error between the measured voltage and detected fundamental wave component of the voltage by using the discrete detector and a sampling time together with a detected frequency of the measured voltage. The detected frequency is detected from a detected difference between positive and negative voltage components of the measured voltage and from an error between the measured voltage and the detected fundamental wave component of the voltage.

    Abstract: A voltage sensor includes an insulator with mutually insulated electrodes embedded therein. The electrodes are coaxial and cylindrical and overlap axially along part of their lengths. They are mutually staggered and control the surfaces of electric equipotential such that there is a substantially homogeneous electric field outside the insulator and a substantially homogeneous but higher field within a sensing cavity within the insulator. A field sensor is arranged within the sensing cavity to measure the field. This design allows for the production of compact voltage sensors for high voltage applications.

    Abstract: The invention is concerned with a resistive fault current limiter (FCL) based on thin superconducting films. The FCL comprises constrictions (2) with a reduced critical current, separated by connecting paths (3). Upon occurrence of a fault current, the former turn resistive simultaneously and build up a resistance which allows the applied voltage to drop entirely only over the constrictions. Only at a later stage, the connecting paths become resistive and dissipate energy. The thickness and width of an electrical bypass determine said normal resistivities of the constrictions and the connecting paths.
