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 Though it will be many years before the both standards are virtually the same, this isc a first step.
The requirements for human safety are not covered by this standard. The way these transmission-line choices will improve or degrade lightning performance is also provided.
The procedures are based on theoretical studies, test results, and experience. In Annex J, some aspects regarding the old type of SiC gapped arresters are discussed. 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.
The user of surge arresters will, 600995 that case, not be required to apply the whole process introduced here to any new installation and the selection of characteristics resulting from prior practice may be continued.
Surge arresters – Part 5: Selection and application recommendations
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.

More complex and special solutions requiring study by experienced engineers is described, but specific solutions are not always given. You may find similar items within these categories by iex from the choices below:. 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.
This guide gives methods for insulation coordination of different air-insulated systems like transmission lines and substations. Part 1 covers the insulation surge withstand strength of motors and generators with windings having form-wound multi-turn coils and the application of surge protection to form-wound multi-turn coil motors. Therefore, the following duties for the metal-oxide surge arresters without gaps and the metal-oxide surge arresters with internal series gap to operate due to slow front overvoltages caused by switching or system faults are not considered for this standard: Surge protective components, current at the date of this publication.
It has to be recognized that this application guide approaches the subject of surge protection from a common or generalized application viewpoint. It covers phase-to-phase, phase-to-earth and longitudinal insulation of three-phase systems with nominal voltages above kec Preview Insulation co-ordination – Part 4: IEC Surge arresters – Part 3: 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.
This edition includes lec following significant technical changes with respect to the previous edition regarding the new surge arrester classification introduced in IEC See Complete Overview C Typical maximum residual voltages are given in Annex 6009-95.

It also gives the lists of the standard withstand voltages from which the rated withstand voltages should be selected. 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 oec. This standard defines the terms used; defines the quantities to be measured; describes test and measuring circuits which may be 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 iex.
September Irc By: Part 5 Selection and application recommendations This 6099-5 provides recommendations for the selection and application of surge arresters to be used in three-phase systems with nominal voltages above 1kV. Complex applications of surge protection practices may require specialized study by experienced engineers.
