This standard is also applicable to single-pole switches used on three phase systems. This standard cancels and replaces the third edition of IEC , published in It constitutes a technical revision.
This edition includes the following significant technical changes with respect to IEC - the rated voltage of 52 kV is now included; - the document is aligned with IEC and IEC ; - addition of a test procedure for short-circuit making tests; - introduction of notion of NSDD non-sustained disruptive discharge as defined in IEC and restrikes; - new classes C1 and C2 for capacitive switching; - new Annex A defining tolerances.
This publication is to be read in conjunction with IEC Ta standard prav tako velja za stikala z enim polom, ki se uporabljajo pri trifaznih sistemih. Prekinjevalna stikala so prav tako zajeta v IEC za njihovo prekinjevalno funkcijo.

IEC specifies requirements for internal arc classification of metal-enclosed pole-mounted switchgear installations used for alternating current with rated voltages above 1 kV and up to and including 52 kV with service frequencies up to and including 60 Hz.
This document is applicable to three-phase, two-phase and single phase equipment. Enclosures may include fixed and removable components and may be filled with fluid liquid or gas to provide insulation. IEC is available as IEC RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition. IEC applies to three-pole-operated fused circuit-switchers designed with rated voltages above 1 kV up to and including 52 kV for use on three-phase alternating current systems of either 50 Hz or 60 Hz.
This third edition cancels and replaces the second edition published in This Part of IEC , which is a Technical Report, refers to prefabricated metal-enclosed and solid-insulation enclosed both hereinafter called enclosed switchgear and controlgear assemblies for alternating current of rated voltages above 1 kV and up to and including 52 kV as specified in IEC and IEC , and to other equipment included in the same enclosure with any possible mutual influence. This Technical Report may be used for the extension of the validity of type tests p This part of IEC is applicable to AC series capacitor by-pass switches designed for outdoor installation and for operation at frequencies of 50 Hz and 60 Hz on systems having voltages above 52 kV.
It is only applicable to by-pass switches for use in three-phase systems. This document is also applicable to the operating devices of by-pass switches and to their auxiliary equipment. IEC covers the connection assembly of fluid-filled and extruded cables to gas-insulated metal enclosed switchgear GIS , in single- or three-phase arrangements where the cable terminations are fluid-filled or dry-type and there is a separating insulating barrier between the cable i This document applies to wrought steel enclosures and their welding.
This document applies to wrought aluminium and aluminium alloy enclosures and their welding. This document applies to welded composite enclosures of cast and wrought aluminium alloy pressurized with dry air, inert gases e.
IEC applies to alternating current disconnectors and earthing switches, designed for indoor and outdoor installations for nominal voltages above 1 V and for service frequencies up to and including 60 Hz.

The following dates were fixed: — latest date by which the EN has to be implemented at national level by publication of an identical dop national standard or by endorsement — latest date by which the national standards conflicting dow with the EN have to be withdrawn Annexes ZA and ZB have been added by CENELEC.
For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document including any amendments applies. Clause Deviation 1. For high-voltage alternating current circuit-breakers containing gas-filled compartments, the design pressure is limited to a maximum of 0,5 bar gauge and the volume is limited to a maximum of 2 m.
This requirement is not applicable for gas filled compartments having a design pressure exceeding 0,5 bar gauge but a volume not exceeding 25 dm.
Moreover, the manufacturer of any electrical equipment, which comprehends gas- pressurized enclosures, must submit the design of the pressurized enclosures itself to a proper legal Authority indicating the stresses and the loads which have any influence on the design itself.
For each of the stresses the manufacturer must indicate the design values and the relevant computations. Only the use of porcelain type A or S Aluminous or Siliceous is permitted.
