What is BS EN 60865-1 - Short-circuit currents about?
BS EN 60865-1 is applicable to the mechanical, and thermal effects of short-circuit currents. It contains procedures for the calculation of:
- The electromagnetic effect on rigid conductors, and flexible conductors
- The thermal effect on bare conductors
Who is BS EN 60865-1 - Short-circuit currents for?
BS EN 60865-1 on short-circuit currents is helpful for:
- Power plants
- Manufacturing units, and for use of machinery
- Solar energy industry
- Automobile industry
- Telecommunications industry
Why should you use BS EN 60865-1 - Short-circuit currents?
Having access to reliable guidelines to determine the mechanical, and thermal effects of short-circuit currents is essential for safely dealing with electrical appliances. BS EN 60865-1 provides manufacturers with the terms, definitions, symbols, and units along with rigid conductor arrangements, and calculation of electromagnetic forces.
BS EN 60865-1 will allow manufacturers to calculate the electromagnetic effect on the specified conductors, and thermal effect on bare conductors. BS EN 60865-1 contributes to safe, and secure use of electrical installations for its users.
What has changed since the last update?
BS EN 60865-1:2012 supersedes EN 60865-1:1993. BS EN 60865-1:2012 includes the following significant technical changes with respect to EN 60865-1:1993:
- The determinations for automatic reclosure together with rigid conductors have been revised
- The influence of mid-span droppers to the span has been included
- For vertical cable-connection the displacement, and the tensile force onto the lower fixing point may now be calculated
- Additional recommendations for foundation load due to tensile forces have been added.
- The subclause for determination of the thermal equivalent short-circuits current has been deleted (it is now part of EN 60909-0)
- The regulations for thermal effects of electrical equipment have been deleted.
- The standard has been reorganized, and some of the symbols have been changed to follow the conceptual characteristic of international standards.
