IEC TR 62681:2022作为IEC TR 62681:2022 RLV提供，其中包含国际标准及其红线版本，显示了与上一版本相比技术内容的所有变化。IEC TR 62681:2022就电磁问题提供了一般指导高压直流架空输电线路的环境问题。它涉及用于描述HVDC架空输电线路电磁特性的主要参数，包括电场、离子电流、磁场、无线电干扰和由于这些影响而产生的可听噪声。如果尚未规范电磁性能的评估方法和/或标准，不同国家的工程师可以参考本文件: -支持/指导高压直流架空输电线路的电磁设计， -将对环境的影响限制在可接受的范围内，以及 ——优化工程成本。

IEC TR 62681:2022 is available as IEC TR 62681:2022 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC TR 62681:2022 provides general guidance on the electromagnetic environment issues of HVDC overhead transmission lines. It concerns the major parameters adopted to describe the electromagnetic properties of an HVDC overhead transmission line, including electric fields, ion current, magnetic fields, radio interference, and audible noise generated as a consequence of such effects. If the evaluation method and/or criteria of electromagnetic properties are not yet regulated, engineers in different countries can refer to this document to:
- support/guide the electromagnetic design of HVDC overhead transmission lines,
- limit the influence on the environment within acceptable ranges, and
- optimize engineering costs.
