Surge arresters – Part 5: Selection and application recommendations
Surge protective devices, and 37B: Surge arresters and low-voltage limiters for specific use in d. What is a standard? They may be associated with other devices such as contactors for self-restoring arrangements.
While some parameters such as voltage, routing, and capacity may be predetermined, other decisions are made at the discretion of the designer. This new edition covers new mechanical test requirements for polymer and porcelain housed arresters. This new amendment now specifies a short circuit test for all arresters.
More complex and special solutions requiring study by experienced engineers is described, but specific solutions are not always given. Surge arresters containing both series and parallel gapped structures – Rated 52 kV and less This standard applies to all metal-oxide surge arresters with gaps and housed in either porcelain or polymeric housings.
Surge protective components, current at the date of this publication. General terms and conditions Cookies och 6009-95 Disclaimer Contact. Worldwide Standards We can source any standard from anywhere in the world.

SS Valve type surge arresters – Terminology. 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 guide recognizes that a perfect line design does not exist, and that a series of compromises are made in any distribution-line design.
These are surge arresters consisting of one or more non-linear resistors which may be in series with single or multiple spark gaps. The recommendations for the capacitor part are given in IEC It covers phase-to-phase, phase-to-earth and longitudinal ieec of three-phase systems with nominal voltages above 1kV Preview Insulation co-ordination – Part 4: They are not used in general to provide surge protection. These considerations apply specifically to electric utility systems and do not recognize the neutral grounding requirements for dispersed storage and generation.
It lec likely, however, that 600999-5 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. 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 60099- voltages above 1kV.

The requirements 60099-5 human safety are not covered by this standard. 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 60099- 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.
The designer may exercise control over structure material and geometry, shielding if anyamount of insulation, grounding, and placement of arresters.

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 Surge arresters – Part 5: The following test report forms are related: Fuses and other overcurrent protection devices Substations, surge arresters. These are protective devices mainly used in fixed installations of d.

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. It also gives the lists of the standard withstand voltages from which the rated withstand voltages should be selected. 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 interference.
