Benefits of Using IEC 61439-1 Standard in Electrical Busbar Systems
Electrical busbar systems are a type of low-voltage switchgear and controlgear assemblies that distribute electrical power using busbars. Busbars are metal bars that carry high currents and connect different electrical components. Busbar systems offer several advantages over conventional cable systems, such as higher efficiency, lower losses, reduced space requirements, easier installation and maintenance, and greater flexibility and scalability.
However, busbar systems also pose some challenges and risks, such as short circuits, overheating, electromagnetic interference, corrosion, and mechanical damage. Therefore, it is essential to ensure that busbar systems are designed, constructed, tested and verified according to the relevant standards and regulations.
One of the most widely used and recognized standards for busbar systems is IEC 61439-1. This standard provides the general rules and requirements for low-voltage switchgear and controlgear assemblies, including busbar systems. It also defines the roles and responsibilities of the original manufacturer and the assembly manufacturer.
By using IEC 61439-1 standard in electrical busbar systems, the following benefits can be achieved:
Safety: The standard ensures that busbar systems are safe for people and plants by specifying the protection objectives against electric shock, fire, thermal effects, overcurrents, mechanical impacts, environmental influences, etc. It also requires design verification by testing, calculation/measurement or application of design rules to prove that the busbar systems meet the safety and performance requirements.
Quality: The standard ensures that busbar systems are of high quality by specifying the construction requirements, technical characteristics and documentation of assemblies. It also requires routine verification by inspection and testing to confirm that each individual assembly complies with the specifications.
Compatibility: The standard ensures that busbar systems are compatible with other components and devices by specifying the service conditions, ratings and characteristics of assemblies. It also provides guidance on how to select and install assemblies according to the application and environment.
Reliability: The standard ensures that busbar systems are reliable and durable by specifying the design life and maintenance intervals of assemblies. It also provides guidance on how to prevent and correct faults and defects in assemblies.
Efficiency: The standard ensures that busbar systems are efficient and economical by specifying the energy efficiency and power loss factors of assemblies. It also provides guidance on how to optimize the design and operation of assemblies to reduce energy consumption and costs.
These are some of the benefits of using IEC 61439-1 standard in electrical busbar systems. By following this standard, manufacturers, installers, operators and users can ensure that their busbar systems are safe, quality-assured, compatible, reliable and efficient. 061ffe29dd
