1   Scope This part of IEC 60146 gives guidance on variations to the specifications given in IEC 60146‑1‑1:2009 to enable the specification to be extended in a controlled form for special cases. Background information is also given on technical points which should facilitate the use of IEC 60146‑1‑1:2009. This technical report primarily covers line commutated converters and is not in itself a specification, except as regards certain auxiliary components, in so far as existing standards may not provide the necessary data.
