Design of earth electrode stations for high-voltage direct current (HVDC) links. General guidelines Ingestion-build-51215 treating industrial wastewater similar to1 Scope This Technical Specification applies to the design of earth electrode stations for high voltage direct current (HVDC) links. It is intended to provide necessary guidelines, limits, and precautions to be followed during the design of earth electrodes to ensure safety of personnel and earth electrodes and prevent any significant impact they may exert on d. c. power transmission systems and the surrounding environment.
