HVDC grounding ; An electrode line is used in some high-voltage direct-current (HVDC) power transmission systems which use the ground or sea as the return path for electric current.
Grounding electrodes are an important part with significant roles in the operation of the HVDC systems. ... In the relevant studies, environmental impacts of HVDC electrodes, e.g. step voltage, effect on the buried metallic structures, DC magnetic power of power transformers and mitigation methods are highlighted here.
