IEC 61854:2020 is available as IEC 61854:2020 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 61854:2020 applies to spacers for conductor bundles of overhead lines. It covers rigid spacers, flexible spacers and spacer dampers. It does not apply to interphase spacers, hoop spacers and bonding spacers. This document is written to cover the line design practices and spacers most commonly used at the time of writing. There may be other spacers available for which the specific tests reported in this document may not be applicable. In some cases, test procedures and test values are left to agreement between purchaser and supplier and are stated in the procurement contract. The purchaser is best able to evaluate the intended service conditions, which should be the basis for establishing the test severity. In Annex A, the minimum technical details to be agreed between purchaser and supplier are listed. This second edition cancels and replaces the first edition published in 1998. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) Consider the application of spacers on high temperature conductors specifying additional high temperature tests in clamp slip tests and for the characterization of elastic and damping properties; b) Specify as far as possible test parameters and acceptance values; c) Avoid as far as possible the alternative procedures for the same test; d) Introduce a simpler test device for the simulated short circuit current test; e) Introduce test at low temperature on fastener components such as break away bolts and conical spring washers; f) Prescribe a different procedure for subspan oscillation tests on spacers equipped with clamps having rod attachments; g) Modify the test procedure for the aeolian vibration tests; h) Prescribe a different procedure for aeolian vibration tests on spacers equipped with clamps having rod attachments; i) Re-edit all the figures in order to make them more clear and homogeneous; j) Introduce an additional test device for the simulated short circuit current test.

IEC 61897:2020 is available as IEC 61897:2020 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition. IEC 61897:2020 applies to aeolian vibration dampers intended for single conductors or earth wires or conductor bundles where dampers are directly attached to each subconductor. The purchaser may adopt part(s) of this document when specifying requirements for cables different from those mentioned above (e.g. optical ground wires (OPGW), all dielectric self-supporting optical cables (ADSS)). In some cases, test procedures and test values are left to agreement between the purchaser and the supplier and are stated in the procurement contract. Annex A lists the minimum technical details to be agreed between purchaser and supplier. Throughout this document, the word “conductor” is used when the test applies to dampers for conductors or earth wires. This second edition cancels and replaces the first edition published in 1998. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) Consider, in addition to Stockbridge type aeolian vibration dampers, also spiral aeolian vibration dampers and elastomeric aeolian vibration dampers. b) Consider the application of dampers on high temperature conductors, specifying additional high temperature tests in clamp slip tests. c) Simplify the procedure of the damper effectiveness evaluation. d) Introduce test at low temperature on fastener components such as break away bolts and conical spring washers. e) Include figures showing the test arrangements for the main mechanical tests. Key words: Overhead Lines, Aeolian Vibration Dampers

Applies to fittings for overhead lines of nominal voltage above 45 kV. It may also be applied to fittings for overhead lines of lower nominal voltage and to similar fittings for substations.

Is applicable to the testing procedures for foundations of overhead line structures.

Superseded by EN 50341-1:2012

This standard applies to bare and covered conductor overhead lines and overhead insulated cable systems with nominal voltage exceeding AC 1 kV up to and including AC 45 kV and with rated frequencies below 100 Hz. In general the requirements in EN 50341-1 apply. This standard specifies additional requirements and simplifications that apply only for this voltage range. In connection with EN 50341-1, this standard specifies the general requirements that shall be met for the design and construction of new overhead lines to ensure that the line is suitable for its purpose with regard to safety of persons, maintenance, operation and environmental considerations. This standard does not apply to: – overhead electric lines inside closed electrical areas as defined in HD 637 S1; – catenary systems of electrified railways unless explicitly required by another standard.

Applicable to testing of towers and structures of overhead lines for voltages above 45 kV. Codifies methods of tests.

Notes 1, 2 and 3 are normative in Austria: NOTE 2 The construction of lines with covered conductors (KUF) and reduced internal or external clearance is permitted in Austria. NOTE 4 This NNA applies to overhead lines with nominal voltage exceeding AC 1kV up to and including AC 45 kV and a maximum operating voltage of 52 kV according to ÖVE EN 60071-1. Hereinafter the latter will be described as high voltage overhead lines, group I.

EN 50423-2:2005 superseded by EN 50341-1:2012 (PR=22540) and each of the EN 50341-2-X series (NNAs)

This standard applies to overhead electric lines with rated voltages exceeding 45 kV AC and with rated frequencies below 100 Hz. This standard specifies the general requirements that shall be met for the design and construction of new overhead lines to ensure that the line is suitable for its purpose with regard to safety of persons, maintenance, operation and environmental considerations. NOTE 1 The extent of the application of this standard by each country in respect of existing overhead lines is subject to the requirements of the National Normative Aspects (NNA) applicable to that country. NOTE 2 Design and construction of overhead lines with insulated conductors, where internal and external clearances can be smaller than specified in the standard are not included. All other requirements of the standard may be applied to overhead lines with insulated conductors. When necessary, requirements for clearances can be given in the NNAs. NOTE 3 This part of the standard is applicable for optical Ground Wires (OPGWs) and optical Conductors (OPCONs). However the standard is not applicable to telecommunication systems which are used on overhead transmission lines either attached to the transmission line conductor/earth wire system (for example wraparound,...) or as separate cables supported by the transmission supports for example All Dielectric Self Supporting (ADSS) or for telecommunication equipment mounted on individual transmission line structures. When necessary, requirements can be given in the NNAs. This standard does not apply to : - overhead electric lines inside closed electrical areas as defined in HD 637; - catenary systems of electrified railways.

Field of application: AT.1 Notes 1, 2 and 3 are normative in Austria: NOTE 1 The extent of the application of this standard is defined in Austrian „Elektrizitätsverordnung – ETV“. NOTE 2 The construction of lines with covered conductors (KUF) and reduced internal or external clearance is not permitted in Austria. For KUF-lines the prescriptions for clearances as from 5.4.2.1 apply. NOTE 3 In addition to the text from Part 1 the following applies: These regulations also cover telecommunication lines which are carried on supports of OH high voltage lines. These regulations are not valid for constructions of conductors or cables with integrated optical fibres independent from their function which do not have simultaneously the function of a conductor or an earth wire. For such constructions the normal additional load as from 4.3.3 and the exceptional additional loads with minimum 12 N/m are to be considered. For such constructions with metallic materials internal clearances as defined in 5.4.2.1 apply.
