Electrode line
Encyclopedia
An electrode line is an electrical connection from a static inverter plant
of a high voltage direct current transmission system to the earth grounding electrode (cathode or anode). The grounding electrode is for the prevention of electro-chemical corrosion and for the avoidance of electromagnetic influence, located some kilometers away from the static inverter station, so for this a separate line connection is necessary. This can be implemented depending upon the situation of the electrode (ashore or in the sea) as ground cables, as overhead line, or as a combination of ground cable and overhead line. Electrode lines are mostly used with systems that have an operating voltage of approx. 10-20kV (medium voltage range).
Static inverter plant
A static inverter station, also known as an HVDC Converter Station, is the terminal equipment for a high-voltage direct-current transmission line, in which direct current is converted to three-phase alternating current, and, usually, the reverse...
