Direct-voltage divider

The invention relates to a direct-voltage divider for high-voltage direct-current transmission systems, couplings and the like, which exhibits a high-voltage and a low-voltage section which are located within a housing filled with insulating oil, the measurement voltage being amplified and conducted to a control centre or the like. To develop a direct-voltage divider further in such a manner that it can also be used for an accurate current measurement in addition to the voltage measurement, it is proposed that on the housing (14) of the direct-voltage divider, a shunt (6) is arranged and an electronics section (4) is arranged and, connected to an auxiliary voltage source supplied with the voltages of the voltage divider (9, 10) and of the shunt (6) and possibly other parameters of the divider and/or the shunt, and the output of which is connected to an A/D converter (5), the digital data of which are conducted via optical fibres (13) to the control centre or the like and are then supplied to a D/A converter and from the latter to a computer.
