Current trends of international standardization activities on ultra-high-voltage technologies

A world economy expands over boundaries between countries and regions. In Japan, there are many splendid technologies which the world requires. In order to transfer these technologies to the world an international standard which includes them as a standard is necessary. Activities by which 1100 kV UHV technologies are standardized in the IEC standard were conducted by starting with discussions in IEC/SB1. The activity has been followed by IEC/JICCG which coordinates IEC and CIGRE activities. The horizontal standards were started in advance at TC 8 and TC 28. The equipment standards will start from 2009 after the CIGRE committee finishes their reports by the end of 2008. Activities by the IEEJ standard committee have been carried horizontally to proceed with the UHV standardization rapidly and efficiently. Copyright © 2009 Institute of Electrical Engineers of Japan.
