  • Very high-voltage DC line voltage sensor
    Patent number: 9766272
    Abstract: The invention provides a voltage sensor for a very high-voltage direct current line comprising two voltage divider stages connected in series, the sensor being characterized in that a first voltage divider stage (E1) that divides the very high voltage to an intermediate voltage is constituted by at least two elementary voltage divider stages (Em) connected in series and distributed in a composite insulator (I), each elementary stage (Em) comprising a resistor Re in parallel with a capacitor Ce, the second voltage divider stage (E2) that delivers the intermediate voltage being constituted by electronic components comprising capacitors and/or interchangeable resistors.
    Type: Grant
