Practices and requirements for semiconductor power rectifier transformers for dedicated loads rated single-phase 300 kW and above and three-phase 500 kW and above are included. Static precipitators, high-voltage converters for dc power transmission, and other nonlinear loads are excluded. Service conditions, both usual and unusual, are specified, or other standards are referenced as appropriate. Routine tests are specified. An informative annex provides several examples of load loss calculations for transformers when subjected to nonsinusoidal currents, based on calculations provided in the standard.

IEEE Standard Practices and Requirements for Semiconductor Power Rectifier Transformers
Practices and requirements for semiconductor power rectifier transformers for dedicated loads rated single-phase 100 kW and above and three-phase 100 kW and above are included. Static precipitators, high-voltage converters for dc power transmission, and other nonlinear loads are excluded. Service conditions, both usual and unusual, are specified, or other standards are referenced as appropriate. Routine tests are specified, and an informative annex provides several examples of load loss calculations for transformers when subjected to nonsinusoidal currents, based on calculations provided in the standard.
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.
No Superseded Standards
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No Inactive-Withdrawn Standards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.

IEEE Standard for Practices and Requirements for Semiconductor Power Rectifier Transformers Amendment 1: Added Technical and Editorial Corrections
Amendment to IEEE Std C57.18.10-1998. This standard practice provides rating data, construction requirements, testing, and calculation methods for dry-type or liquid-filled semiconductor power rectifier transformers. These transformers supply nonsinusoidal load currents and are subject to higher harmonic load losses than standard power transformers. A number of examples illustrating harmonic loss calculations are presented in a reference annex.
