This part of IEC 60071 provides guidance on the procedures for insulation co-ordination of high-voltage direct current (HVDC) converter stations, without prescribing standardized insulation levels. This standard applies only for HVDC applications in high-voltage a.c. power systems and not for industrial conversion equipment. Principles and guidance given are for insulation co-ordination purposes only. The requirements for human safety are not covered by this application guideline. The responsible committee is DKE/K 122 "Isolationskoordination" ("Insulation co-ordination") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
