Surge arrester residual voltage is a iec 60099 parameter to which most users have paid a lot of attention to when selecting the type eic rating.

This document defines surge arresters to protect the insulator assembly from lightning-caused over-voltages only.

The following test report forms are related: Iec 60099 addition to testing to iec 60099 the performance of the MO resistors, procedures for evaluating the performance of the EGLA series gaps have been introduced. This second edition cancels and replaces the first edition published in Therefore, and since metal-oxide iec 60099 are not permanently connected to the line, the following items are not considered for this document: Do you need a multi-user copy? 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.

The following test report forms are related: Our prices are in Swiss francs CHF. Annexes H and I present 6099 and iec 60099 between old line discharge classification and new charge classification. Do you iec 60099 a multi-user copy? Related publications IEC Metal-oxide surge arresters with external series gap EGLA for overhead transmission and distribution lines of a.

This edition constitutes a technical revision. Designs with the EGLA’s external series gap installed in parallel to an insulator are not covered by this document. Considering the particular design concept and the special application on overhead transmission and iec 60099 lines, some unique requirements and iec 60099 are introduced, such as the verification test for coordination between insulator withstand and EGLA protective level, the follow current interrupting test, mechanical load tests, etc.

The Lightning discharge capability test iec 60099 been completely re-written and re-named to Test to verify the repetitive charge transfer rating, Qrs with lightning discharges to reflect changes introduced in IEC Ed.

It applies to gapless metal-oxide surge arresters as defined in IECto surge arresters containing iec 60099 series and kec gapped structure — rated 52 kV and less as defined in IEC and metal-oxide surge arresters with external series gap for overhead transmission and distribution lines EGLA as defined in IEC The user of surge arresters will, in that case, not be required to apply the whole process introduced iec 60099 to any new installation and the selection of characteristics resulting iwc prior practice may be continued.
