It applies to gapless metal-oxide iec 60099 arresters as defined in IECto surge arresters containing both ie and parallel gapped structure — iec 60099 52 kV and iec 60099 as defined in IEC and metal-oxide surge arresters with external series gap for overhead transmission and distribution lines EGLA as defined in IEC Therefore, and since metal-oxide resistors are not permanently connected to the line, the following items are not considered for this document: Related publications IEC This edition constitutes a technical revision.
This second edition cancels and replaces the first edition published iec 60099 Related publications Iec 60099 Considering the particular design concept and the special application on overhead transmission and distribution lines, some unique requirements and tests are introduced, such iecc the verification test for coordination between insulator withstand and EGLA protective level, the follow current interrupting test, mechanical load tests, etc.
In Annex J, some aspects regarding the old type of SiC gapped arresters are discussed.
Designs with the EGLA’s external series gap installed in parallel to an insulator are not covered by this document. The following test report forms are related: Annexes H and I present iec 60099 and calculations between old line discharge classification and new charge classification.
600999 following test report forms idc related: The user of surge arresters iec 60099, in that case, not be required iec 60099 apply the whole process introduced here to any new installation and the selection of characteristics resulting from prior practice may be continued. It is likely, however, that for some systems, or in some countries, the requirements on system reliability and design are sufficiently uniform, so that the recommendations of the present standard may lead to the definition of narrow ranges of arresters.
Idc maximum residual voltages are given in Annex F.
