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.Technology -

It is primarily meant for the operators of electric power networks, particularly those of public power supplies, including High-Voltage DC transmission (HVDC). This scope does not include:
– railway networks,
– installations of end consumer networks,
– installations for electric power generation.
Crises handling, e.g. in emergency situations, is not within the scope of this document.Technology -
Technical committeeTypeAcronymIEC TS 63014-1:2018CommitteePublished year2018KeywordsDescription
IEC TS 63014-1:2018(E) is intended to provide an overall and consistent set of guidelines to facilitate the specification of equipment for the DC-side of a high-voltage direct current (HVDC) system using line-commutated converters. For point-to-point HVDC transmission systems, this document covers all DC-side equipment located between the converter valves and the DC overhead line or cable termination, excluding the converter valves themselves. For back-to-back HVDC systems, this document covers all DC-side equipment excluding the converter valves themselves.

Technical committeeTypeAcronymIEC TS 62344:2013CommitteePublished year2013KeywordsDescription
IEC/TS 62344:2013(E) applies to the design of earth electrode stations for high-voltage direct current (HVDC) links. It is intended to provide necessary guidelines, limits, and precautions to be followed during the design of earth electrodes to ensure safety of personnel and earth electrodes and prevent any significant impact they may exert on d.c. power transmission systems and the surrounding environment. This technical specification cancels and replaces IEC/PAS 62344 published in 2007. This first edition constitutes a technical revision.

Technical committeeTypeAcronymIEC TS 61973:2012+AMD1:2019CommitteePublished year2019KeywordsDescription
IEC TS 61973:2012+A1:2019 applies to the specification and evaluation of outdoor audible noise from high voltage direct current (HVDC) substations. It is intended to be primarily for the use of the utilities and consultants who are responsible for issuing technical specifications for new HVDC projects with and evaluating designs proposed by prospective contractors. It is primarily intended for HVDC projects with line-commutated converters. Part of this technical specification can also be used for the same purpose for HVDC projects using voltage sourced converters, and for flexible a.c. transmission systems (FACTS) devices such as static Var compensators (SVCs) and static synchronous compensators (STATCOMs). This consolidated version consists of the first edition (2012) and its amendment 1 (2019). Therefore, no need to order amendment in addition to this publication.

Technical committeeTypeAcronymIEC TS 60076-23:2018CommitteePublished year2018KeywordsDescription
IEC TS 60076-23:2018(E) specifies requirements for devices for the suppression of DC magnetic bias of power transformers and convertor transformers. It includes requirements for service conditions, structures, testing, packing, transport and storage.
The devices are connected to neutral points of power transformers and converter transformers to suppress DC bias current in the case an HVDC system is operated in monopole ground return mode or bipolar unbalanced mode. In the case of dedicated metallic return HVDC system, the devices are useful to mitigate DC stray current flowing through power transformers and converter transformers during transient conditions such as DC line fault.
This document applies to DC magnetic bias suppression devices for operation at frequencies of 50 Hz and 60 Hz on power systems having voltages above 110 kV.

Technical committeeTypeAcronymIEC TR 63179-1:2020CommitteePublished year2020KeywordsDescription
IEC TR 63179-1:2020 (E) provides guidelines for the selection of a high-voltage directive current (HVDC) system with line-commutated converters (LCC), hereafter referred to as HVDC system, for the purposes of HVDC system planning. It covers the guidelines on the requirements for integrating HVDC systems in AC power networks, selection of rated voltage and power, overloads, circuit configuration, expandability, comparison of technical, economic, regulatory, political, social and environmental factors, etc.
This document is applicable for planning an HVDC system. This guideline is not exhaustive and it is possible that there will be other specific aspects, particular to a specific HVDC project, which will also need to be considered.Technology -
