Annotation of standard text IEC 62501-ed.2.0-CMV :
IEC 62501:2024 CMV contains both the official standard and its commented version. The commented version provides you with a quick and easy way to compare all the changes between IEC 62501:2024 edition 2.0 and the previous IEC 62501:2009+AMD1:2014+AMD2:2017 CSV edition 1.2. Furthermore, comments from IEC SC 22F experts are provided to explain the reasons of the most relevant changes, or to clarify any part of the content. IEC 62501:2024 applies to self-commutated converter valves, for use in a three-phase bridge voltage sourced converter (VSC) for high voltage DC power transmission or as part of a back-to-back link, and to dynamic braking valves. It is restricted to electrical type and production tests. This document can be used as a guide for testing of high-voltage VSC valves used in energy storage systems (ESS). The tests specified in this document are based on air insulated valves. The test requirements and acceptance criteria can be used for guidance to specify the electrical type and production tests of other types of valves. This edition includes the following significant technical changes with respect to the previous edition: a) Conditions for use of evidence in lieu are inserted as a new Table 1; b) Test parameters for valve support DC voltage test, 7.3.2, and MVU DC voltage test, 8.4.1, updated; c) AC-DC voltage test between valve terminals, Clause 9, is restructured and alternative tests, by individual AC and DC voltage tests, added in 9.4.2; d) Partial discharge test in routine test program is removed; e) More information on valve component fault tolerance, Annex B, is added; f) Valve losses determination is added as Annex C.
