高压直流输电线路参数测量指南

[中文适用范围]： IEC TR 63502:2024 是一份技术报告，它提供了与现场高压直流输电线路参数测量相关的信息。高压直流输电线路可以是架空线、陆地或海底电缆，也可以是具有架空线段和电缆段的混合线（或这些的任意组合）。该文件介绍了测量规范，包括测量条件、安全预防措施、测量仪器、测量方法等，以测量直流电压等级高于 100 kV 的高压直流架空输电线路和电缆的参数。该文件还与高压直流输电系统中接地电极线的线路参数测量有关。 [外文原描述]： 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.
