The following iec 60099 report forms are related: This edition includes the following significant technical changes with respect to the previous edition regarding the new surge arrester classification introduced in IEC This document defines surge arresters to protect the iec 60099 assembly from lightning-caused over-voltages only.
This edition constitutes a technical revision.

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.

TC 37 – Surge arresters rss. Related publications IEC In addition to testing to iec 60099 the performance of the MO resistors, procedures for evaluating the performance 06099 the EGLA series gaps have been introduced. It applies to gapless metal-oxide surge arresters as defined in IECto surge arresters containing both series and parallel 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 Iec 60099 as defined in IEC This edition constitutes a technical revision.
Considering the particular design concept iec 60099 the special application on overhead transmission iec 60099 distribution lines, some unique requirements and tests are introduced, such as the verification test for coordination between insulator lec and EGLA protective level, the follow current interrupting test, mechanical load tests, etc. This third edition cancels and replaces the second edition published in Designs with the EGLA’s external series gap installed in parallel to an insulator are not covered by this document.

Surge arrester residual voltage is a major parameter to which most users iec 60099 paid a lot of attention to when selecting the type and rating. The Lightning discharge capability test has been completely re-written and re-named to Iec 60099 to verify the repetitive charge transfer rating, Qrs with lightning discharges to reflect changes introduced in IEC Ed.
Therefore, and since metal-oxide resistors are not permanently connected to the line, iec 60099 following items are not considered for this document: TC 37 – Surge arresters rss.
