Annotation of standard text IEC/TR 63502-ed.1.0 :

IEC TR 63502:2024, which is a Technical Report, gives information relevant to the on-site HVDC transmission line parameter measurement. HVDC transmission line can be overhead lines, land or submarine cables, or hybrid lines with overhead line section(s) and cable section(s) (or any combination of these). This document introduces measurement specification, including measurement conditions, safety precautions, measurement instrument, measurement methods, etc., in order to measure the parameters of HVDC overhead transmission line and cable with a DC voltage level above 100 kV. This document is also relevant to line parameter measurement of earth electrode lines in HVDC power transmission systems.
