IEC 60099 4 PDF

Although it was hoped to have this completed by the end of , it soon became clear that complete harmonization of these standards was not going to be possible. It was therefore decided to move ahead with informal harmonization by developing similar, though not identical, test methods that could be adopted by both standards bodies as part of their normal cycles and organizations. A second goal when this process began was to create a set of tests that applied to transmission line arresters. For example, mechanical tests applicable to this type of arrester are not covered in C There are some minor differences in this section but if a short circuit test is completed for IEEE certification, with minor modification it can also be applied toward IEC certification. Further to harmonization efforts, Edition 3.

Overview of IEC Standards' recommendations for lightning protection of electrical high-voltage power systems using surge arresters Abstract: This contribution deals with the emerging standards of the IEC series on high-voltage surge arresters. Driven by the demand from UHV systems and by new, experimentally found insights on energy handling capability of metal-oxide MO varistors, a new classification concept and new test requirements have been introduced to the latest edition of the main arrester standard - IEC , Ed.

The major alterations in IEC , especially those regarding arrester classification, energy handling definitions and test requirements are presented and discussed, and detailed background information is given. Another focus of this contribution is on externally gapped line arresters EGLA , which are covered by a separate test standard, IEC This standard was published in and is thus not really new, but its application is not yet generally established, though EGLAs constitute an effective solution for improving the overall performance of transmission and distribution lines.

Recent findings on energy handling capability are of special interest for this application. Article :. DOI: Need Help?
