Considering the particular design concept and the special application on overhead transmission and distribution lines, some unique requirements and tests are introduced, such as the verification test for iex between insulator withstand and EGLA protective level, the follow current interrupting test, mechanical load iec 60099, etc.
This document defines surge arresters to protect the insulator assembly from lightning-caused over-voltages only. This edition includes the following significant technical iec 60099 with respect iec 60099 the previous edition: This edition includes the following significant technical changes with respect to the previous iec 60099 regarding the new surge arrester classification introduced in IEC Typical maximum residual voltages are given in Annex F.
The user of surge arresters will, 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 iecc may be continued. This edition constitutes a technical iec 60099. Annexes H and I present comparisons and calculations between old line discharge classification and new charge classification.
Related publications IEC 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.
