This content has been transferred from the main text, since today's predominant bushing technology does not suffer from flashover during conditions of uneven wetting, in comparison to the earlier used ceramic insulators. Today's outdoor bushings in HVDC applications are made with composite insulators with silicon sheds with well proven hydrophobicity. Furthermore, there exist no verified test method with sufficient reproducibility between different laboratories. It is also difficult for operators to have full knowledge or clear data on how to arrange a test setup that reflects actual site conditions. Subsequently, uneven wetting test is not relevant for composite insulators. The testing may still be performed to outdoor bushings, particularly with ceramic insulators, but shall be agreed between purchaser and manufacturer.

Other Activities From This Working Group
Current projects that have been authorized by the IEEE SA Standards Board to develop a standard.
No Active Projects
Standards approved by the IEEE SA Standards Board that are within the 10-year lifecycle.
No Active Standards
These standards have been replaced with a revised version of the standard, or by a compilation of the original active standard and all its existing amendments, corrigenda, and errata.
C57.19.03-1996
IEEE Standard Requirements, Terminology, and Test Code for Bushings for DC Applications
This standard applies to outdoor and indoor power apparatus dc bushings of condenser type that have basic impulse insulation levels of 110 kV and above for use as components of oil-filled converter transformers and smoothing reactors, as well as air-to-air dc bushings. This standard defines the special terms used, service conditions, rating, general requirements, electrical insulation characteristics, and test procedure for the bushings for dc application.
C57.19.03-1996/Cor 1-2005
IEEE Standard Requirements, Terminology, and Test Code for Bushings for DC Applications - Corrigendum 1
This corrigendum corrects IEEE Std C57.19.03-1996. The standard applies to outdoor and indoor power apparatus dc bushings of condenser type that have basic impulse insulation levels of 110 kV and above for use as components of oil-filled converter transformers and smoothing reactors, as well as air-to-air dc bushings. This standard defines the special terms used, service conditions, rating, general requirements, electrical insulation characteristics, and test procedure for the bushings for dc application
These standards have been removed from active status through a ballot where the standard is made inactive as a consensus decision of a balloting group.
No Inactive-Withdrawn Standards
These standards are removed from active status through an administrative process for standards that have not undergone a revision process within 10 years.
65700-19-03-2014
IEC/IEEE International Standard -- Bushings for DC application
In this first edition of IEC/IEEE 65700-19-03, service experiences as well as established market requirements have been harmonized with existing IEC and IEEE standards
