Surge arresters – Part 5: Selection and application recommendations
While some parameters such as voltage, routing, and capacity may be predetermined, other decisions are made at the discretion of the designer. The methods of analysis are illustrated by practical examples.
The requirements for human safety are not covered by this standard. IEEE IEEE Standard for Series Capacitors in Power Systems Capacitors and assemblies of capacitors, insulation means, switching, protective equipment, and control accessories that form a complete bank for inserting in series with a transmission line are applied.
Preview Abstract IEC Surge arrester residual voltage is a major parameter to which most users have paid a lot of attention to when selecting the type and rating. This third edition cancels and replaces the second edition published in Systematic directions toward proper solutions of various applications are provided. 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.
September Replaced By: Related publications IEC Protective equipment is defined as the main circuit apparatus and ancillary equipment, which are part of a series capacitor installation, but which are external to the capacitor part itself.

kec This new edition covers new mechanical test requirements for polymer and porcelain housed arresters. You may experience issues viewing this site in Internet Explorer 9, 10 or We accept all major credit cards American Express, Mastercard and VisaPayPal and bank transfers as form of payment. They may be associated with other devices such as contactors for self-restoring arrangements.
This edition constitutes a technical revision. This association is for insulation co-ordination purposes only. This guide will help the distribution-line designer optimize the line design in light of cost benefit considerations.
It specifies the procedure for the selection of the rated withstand voltages for the phase-to-earth, phase-to-phase and longitudinal insulation of the equipment oec the installations of these systems. Where technical information is not readily available, guidance is provided to aid toward proper surge protection and to reduce interference to communication, control, and protection circuits due to surges and other overvoltages.

Click to learn more. This standard recommends that the selected withstand voltages should be associated with the highest voltage for equipment. The designer may exercise control over structure material and geometry, shielding if anyamount of insulation, grounding, and placement of arresters.
They are not used in general to provide surge protection. Preview Insulation co-ordination – Part 2: Iev 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.
In Annex J, some aspects regarding the old type of SiC gapped arresters idc discussed. Definitions, principles and rules Uec part of IEC applies to three-phase a. Computational guide to insulation co-ordination and modeling of electrical networks This technical report gives guidance on conducting insulation co-ordination studies which propose internationally recognized recommendations for the numerical modeling of electrical systems including arresters and for the implementation of deterministic and probabilistic methods adapted to the use of numerical programs.
Though it will be many years before the both standards are virtually the same, this is a isc step. Part 5 Selection and application recommendations This standard provides recommendations for the selection and application of surge arresters to be used in three-phase systems with nominal voltages above 1kV. Glossary of terms 6009-95 definitions from IEC publications,, and This standard provides a list of terms and definitions relative to IEC publications from IEC technical committee It applies to non-linear resistor type gapped surge arresters as defined in IEC and to gapless metal-oxide surge arresters as defined in IEC Take the smart route to manage medical device compliance.
Part 1 covers the insulation surge withstand strength of motors iecc generators with windings having form-wound multi-turn coils and the application of surge protection to form-wound multi-turn coil motors. This edition includes the following significant technical changes with respect to the previous edition regarding the new surge arrester classification introduced in IEC
