Abstract: Voltage sensor (1) comprising a voltage divider (40) for sensing an AC voltage of a HV/MV power conductor (10). For adjusting the common overall impedance of the low-voltage portion of the voltage divider towards a desired impedance, the low-voltage portion (60) comprises one or more low-voltage impedance elements (110), a plurality of adjustment impedance elements (80) and a plurality of switches. In its connect state, each switch electrically connects an adjustment impedance element in parallel to at least one of the one or more low-voltage impedance elements (110). The overall impedance of the high-voltage portion (50) and the overall impedance of the low-voltage portion (60) of the voltage divider (40) are adapted such that, by bringing one or more of the switches (90) into their connect state, the voltage divider (40) has, for an AC voltage of between 5 and 25 kV phase-to-ground and a frequency of between 40 and 70 Hertz, a dividing ratio of 3077, of 6154, of 6769 or of 10 000.

Abstract: Impedance assembly (2) for use in a voltage divider for sensing an AC voltage of at least 1 kV versus ground of a power-carrying conductor distributing electrical energy in a grid. The impedance assembly comprises a) a printed circuit board (131) comprising one or more dielectric board layers (210, 215, 220), b) an externally accessible high-voltage contact (100), c) an externally accessible low-voltage contact (110), spaced from the high-voltage contact by at least 30 mm, and d) at least two dividing capacitors (91), connected in series between the high-voltage contact and the low-voltage contact and operable as a high-voltage side of the voltage divider. Each dividing capacitor has two electrodes formed by conductive areas (301, 302, 303, 304, 305, 306), arranged on opposed surface portions of a specific dielectric board layer, and a dielectric comprising a portion of the specific dielectric board layer on which the electrodes are arranged. Instead of the dividing capacitors, the impedance assembly may comprise a resistor layer.

Abstract: The present invention provides a non-return valve for a resin injection system, especially for use in electrical cable joints, comprising: a valve housing which includes an outlet for a fluid flowing through the valve; and a valve body which is held by the valve housing and is freely movable between a closed position, in which the outlet is substantially sealed or closed to fluid flow by the valve body, and an open position, in which the outlet is substantially open to fluid flow. Thus, with the present invention, the valve body can be loosely held by the valve housing and the valve need not include any spring means to bias the valve body to the closed position. The invention also provides a resin injection system for sealing a localized breach in an object, such as an electrical cable joint.
