HVDC Divider Compensated voltage divider for HVDC transmission systems

Composite Insulator with: SF6 Gas Mineral Oil Porcelain Insulator with: Mineral Oil Composite Insulator with: SF6 Gas Mineral Oil Steel tank with: SF6 Gas For measuring of high DC voltage at HVDC-transmission systems, compensated resistive voltage divider (RC-Divider) are in use. This design ensures a wide bandwidth from DC to several kHz with a fast response to voltage changes. The output voltage signal can then be processed individually. The resistive component is made of high-precision low inductance resistors, connected in series according to the primary rated voltage and the defined measuring...
