Electromagnetic performance of high voltage direct current (HVDC) overhead transmission lines

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.
