What is BS EN 61472 - Minimum approach distances for a.c systems about?
BS EN 61472 is a British standard which describes a method for calculating the minimum approach distances for live working, at maximum voltages between 72,5 kV, and 800 kV.
BS EN 61472 addresses system over voltages, and the working air distances or tool insulation between parts, and/or workers at different electric potentials.
Who is BS EN 61472 - Minimum approach distances for a.c systems for?
BS EN 61472 on minimum approach distances for a.c systems is helpful for:
- Manufacturing factories
- Automobile industry
- Construction, and building
- Power plants
- Telecommunication industry
Why should you use BS EN 61472 - Minimum approach distances for a.c systems?
Determining the minimum approach distances for a.c systems is essential to ensure a secure environment for the workers. BS EN 61472 provides manufacturers with the terms, definitions, and symbols, the factors influencing calculations, and the evaluation of risks which will allows them to calculate the minimum approach distances for a.c systems.
BS EN 61472 contributes to safe, and secure installation, and application of electrical appliances for its users.
What has changed since the last update?
BS EN 61472:2013 superseded EN 61472:2004 which has been withdrawn. BS EN 61472:2013 includes the following significant technical changes with respect to EN 61472:2004:
- Clarification of the scope
- Review of the definitions
- Clarification of the methodology of determining whether live working is permissible, and the calculation of the minimum approach distances
- Modification of the basic equation for calculation of the minimum approach distance
- Introduction of Table 1 for altitude correction factor simplification ka
