This guide recognizes that a perfect line design does not exist, and that a series of compromises are made in any distribution-line design. This new edition covers new mechanical test requirements for polymer and porcelain housed arresters. Though it will be many years before the both standards are isc the same, this is a first lec. IEC Surge arresters – Part 3: Our prices are in Swiss francs CHF. Fuses and other overcurrent protection devices Substations, surge arresters.

Systematic directions toward kec solutions of various applications are provided. The designer may exercise control over structure material and geometry, shielding if anyamount of insulation, grounding, and placement of arresters. Protective equipment for series capacitor banks This part of IEC covers protective equipment for series capacitor banks, with a size larger than 10 Mvar per phase.
You may experience issues viewing this site in Internet Explorer 9, 10 or IEC Surge arresters – Part 1: This guide will help the distribution-line designer optimize the line design in light of cost benefit considerations. Subscribe on standards with our subscription service.
Your shopping cart is empty. This standard also specifies requirements and tests for metal-oxide surge arresters with internal series gaps, with rated voltages of 52KV and below Preview Surge arresters – Part 7: In many cases, the prescribed steps are adequate. While some parameters such as voltage, routing, and capacity may be predetermined, other decisions are made at the discretion of the designer. The protective equipment is mentioned in clauses 1.
This standard is not maintained and applies to products not manufactured any longer. An additional section discusses several special methods that may be used to improve lightning performance.
Surge protective devices, and 37B: What makes this amendment so unique is that it is virtually identical to the test procedure published in IEC in Annexes H and I present comparisons and calculations between old line discharge classification and new charge classification.
Selection and application recommendations Article no: Preview Insulation co-ordination – Part 2: Included are requirements for safety, rating, and protective device levels. Selection and application recommendations Status: Considering the particular design concept and the special application on overhead transmission and distribution lines, some unique requirements and tests are introduced, such as verification test for coordination between insulator and EGLA withstand, follow current interrupting test, mechanical load tests etc.
BS EN 60099-5:2013
The user of surge arresters will, in that case, not be required iex apply the whole process introduced here to any new installation and the selection of characteristics resulting from prior practice may be continued.
Your basket is empty. The Redline version is not an official document, it is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition.
We accept all major credit cards American Express, Mastercard and VisaPayPal and bank transfers as form of payment. These are surge arresters consisting of one or more non-linear resistors which may be in series with single or multiple spark gaps. Glossary of terms and definitions from IEC publications,, and This standard provides a list of terms and definitions relative to IEC publications from IEC technical committee Preview High-voltage test techniques – Partial discharge measurements This International Standard is applicable to the measurement of partial discharges which occur in electrical apparatus, components or systems when tested with alternating voltages up to Hz or with direct voltage.
Please note that the selected standard is invalid. September Replaced By: Non-linear resistor type gapped surge arresters for a. Application guide This standard gives guidance for the determination of the rated withstand voltages for ranges I and II of IEC and justifies the association of these rated values with the standardized highest voltages for equipment.
See Complete Overview C 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.
In Annex J, some aspects regarding the old type of SiC gapped arresters are discussed.
This standard defines the terms used; defines the quantities to be measured; describes test and measuring circuits which may jec used; defines analogue and digital measuring methods required for common applications; specifies methods for calibration and requirements of instruments used for calibration; gives guidance on test procedures; gives some assistance concerning the discrimination of partial discharges from external interference.
Take the smart route to manage medical device compliance. The faster, easier way to work with standards. It also gives the lists of the standard withstand voltages from which the rated withstand voltages should be selected. It has to be recognized that this application guide approaches the subject of surge protection from a common or generalized application viewpoint. This standard applies to devices for separate mounting and to devices supplied integrally with other equipment.
