What is BS EN IEC 61936‑1 about?
BS EN IEC 61936‑1 is the first part of the IEC 61936 multi-series. BS EN IEC 61936‑1 provides requirements for the design and the erection of electrical power installations in systems with nominal voltages exceeding 1 kV AC and nominal frequency up to and including 60 Hz, to provide safety and proper functioning for the use intended.
Note 1: The electrical power installation includes, among others, the following equipment- rotating electrical machines, switchgear, transformers and reactors, converters, cables, wiring systems, batteries, capacitors, earthing systems, buildings and fences which are part of a closed electrical operating area, associated protection, control and auxiliary systems, large air-core reactor.
Note 2: BS EN IEC 61936‑1 does not apply to the design and erection of any of the following- overhead and underground lines between separate electrical power installations, electrified railway tracks and rolling stock, mining equipment and installations, fluorescent lamp installations, installations on ships according to IEC 60092 (all parts) and offshore units according to IEC 61892 (all parts), which are used in the offshore petroleum industry for drilling, processing and storage purposes, electrostatic equipment (e.g. electrostatic precipitators, spray-painting units), test sites, medical equipment, e.g. medical X-ray equipment.
Note 3: BS EN IEC 61936‑1 does not apply to the design of prefabricated, type-tested switchgear and high voltage/low voltage prefabricated substation, for which separate IEC standards exist.
Note 4: The scope of BS EN IEC 61936‑1 does not include the requirements for carrying out live working on electrical power installations.
Note 5: The scope of BS EN IEC 61936‑1 considers safety requirements for HV installations and the influences of HV installations on LV installations. For electrical installations up to 1 kV, IEC 60364 (all parts) applies
Who is BS EN IEC 61936‑1 for?
BS EN IEC 61936‑1 on power installations applies to:
- The electrical system operators in a factory
- Government authorities
- Industrial plant operators
- Any organization in the energy sector
Why should you use BS EN IEC 61936‑1?
Power installations are carried out all across the globe as a part of the development/industrial projects. This process keeps on evolving as there are new developments made, new issues faced new safety concerns.
BS EN IEC 61936‑1 contains the requirements for the design, erection, and verification of high voltage power installations greater than 1 kV ac. The guidelines are intended to provide for the safety of persons, livestock and property against dangers and damage that may arise in the reasonable use of such electrical installations and provide for the proper functioning of those installations.
BS EN IEC 61936‑1, follows worldwide feedback to improve clarity. BS EN IEC 61936‑1 continues the effort towards the alignment all over the world of practices concerning the design and erection of high voltage power installations. While National standards and regulations take precedence, jurisdictions may elect to adopt the requirements of BS EN IEC 61936‑1.
BS EN IEC 61936‑1 can ensure that the high voltage power installation process for your projects is carried out in an efficient manner and safely.
What’s changed since the last update?
BS EN IEC 61936‑1:2021 supersedes BS EN 61936‑1:2010+A1:2014. BS EN IEC 61936‑1:2021 includes some technical changes concerning BS EN 61936‑1:2010+A1:2014. These include:
- The scope has been improved to clarify the application of this document
- Missing and obsolete terms and definitions have been updated including improvement of existing terms
- Table 1 has been updated where agreements between supplier and user are needed
- Requirements of electromagnetic compatibility have been clarified
- Insulation coordination clause (clause 5) has improved wording for better clarity
A Commented Version (CMV) of this standard is available here. Please note, the CMV of the standard is not adopted, and therefore doesn’t contain an additional national foreword, or national annex that might be contained in the BS adoption of the standard. However the IEC text that forms the content of the standard is identical to the BS adoption of the standard.
Commented Versions (CMVs) are specialized publications featuring detailed commentary from technical experts on the major changes between the new edition of a standard and the previous one. Comments may include an explanation for the changes as well as information on the impact of these changes on the application and usability of the standard.
