Application Summary AI generated
This standard specifies technical requirements, test methods, and acceptance criteria for high-voltage direct-current (HVDC) disconnectors and earthing switches rated above 1 kV. It is applied in HVDC transmission systems, including converter stations and DC switchyards, to ensure safe isolation and grounding of circuits during maintenance or fault conditions. The standard is used by manufacturers, utilities, and testing laboratories for design verification and type testing of equipment in long-distance power transmission projects.
