This part of IEC 61378 applies to oil-immersed three-phase and -single-phase convertor transformers for use in HVDC power transmission. It applies to transformers having two, three or multiple windings. This standard does not apply to convertor transformers for industrial applications (see IEC 61378-1) and to convertor transformers for traction applications (see IEC 60310).
IEC/IEEE 60076-57-129:2017(E) specifies requirements of liquid-immersed three-phase and single-phase converter transformers for use in high voltage direct current (HVDC) power transmission systems including back-to-back applications. It applies to transformers having two, three or multiple windings. This document does not apply to: - converter transformers for industrial applications (see IEC 61378-1 or IEEE C57.18.10); - converter transformers for traction applications (see IEC 60310). This publication cancels and replaces the first edition of IEC 61378-2 published in 2001 and IEEE Std C57.129™ published in 2007.
