IEC TS 62344:2013

Design of earth electrode stations for high-voltage direct current (HVDC) links - General guidelines

IEC/TS 62344:2013(E) 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. This technical specification cancels and replaces IEC/PAS 62344 published in 2007. This first edition constitutes a technical revision.
