Semiconductor convertors. General requirements and line commutated convertors - Transformers and reactors Ingestion-build-177197 8 Preparation of the test1 Scope This Part 1 3 of the International Standard relates, in general, to those characteristics wherein convertor transformers differ from ordinary power transformers. In all other respects, the rules specified in IEC 76 shall apply to convertor transformers also, as far as they are not in contradiction with this standard. It should be borne in mind that a rectifier transformer operates with non sinusoidal current waveshape. In single way
