On-Site Assembly, On-Site Rebuild, and On-Site High Voltage Testing of Power Transformers

The aim of the Working Group was to address the new challenges presented by on-site assembly, on-site rebuild, and on-site high voltage testing. New work techniques for large power transformers had to be developed in many countries due to restrictive transportation regulations. This technical brochure shows, by way of a collection of international experiences, some of the best practices and it summarizes the quality assurance system required to ensure the reliability of on-site work.
