IEC 60700-1:2015/COR1:2017

IEC 60700-1:2015/COR1:2017 is a corrigendum to Corrigendum 1 - Thyristor valves for high voltage direct current (HVDC) power transmission - Part 1: Electrical testing, providing a supporting correction to the parent document IEC 60700-1:2015. It is relevant for teams involved in technical review, test planning, and conformity assessment for HVDC thyristor valve electrical testing. As a derived reference, IEC 60700-1:2015/COR1:2017 should be used to keep engineering documentation and verification activities aligned with the corrected published text.

Purpose of IEC 60700-1:2015/COR1:2017

The purpose of IEC 60700-1:2015/COR1:2017 is to amend or clarify the parent testing document for thyristor valves used in high voltage direct current power transmission. In practice, a corrigendum helps ensure that electrical testing requirements are read and applied correctly during laboratory evaluation, documented evaluation, and technical validation. For organizations managing HVDC equipment specifications, it supports more accurate interpretation of the testing standard and reduces the risk of using outdated or inconsistent text in engineering documentation.

Compliance applications of IEC 60700-1:2015/COR1:2017

IEC 60700-1:2015/COR1:2017 is typically used alongside the parent reference during procurement review, test procedure preparation, and compliance workflows for HVDC thyristor valve projects. It may be consulted by manufacturers, testing laboratories, system integrators, and certification teams when confirming electrical test requirements for high-voltage power transmission equipment. In regulated project environments, the corrigendum helps maintain operational consistency across technical assessments, quality workflows, and conformity assessment records tied to the corrected document set.

Benefits of IEC 60700-1:2015/COR1:2017

Using IEC 60700-1:2015/COR1:2017 helps organizations reduce ambiguity in electrical test interpretation and improves confidence in compliance preparation for HVDC valve systems. For engineering and quality teams, it supports safer testing practices, more reliable verification activities, and better alignment between specifications and executed test plans. It can also streamline procurement and supplier review by ensuring that the latest corrected reference is applied during technical evaluation, helping to lower risk and improve consistency across testing and documentation.
