What is BS EN 61800-7-4:2018?

BS EN 61800-7-4:2018 is a technical standard that establishes the requirements and recommendations for adjustable speed electrical power drive systems (PDS) in terms of their compatibility with the power supply network. This standard applies to both low voltage and medium voltage PDS, with a rated output voltage not exceeding 35 kV AC.

Key Requirements of BS EN 61800-7-4:2018

One of the key requirements of this standard is to ensure the compatibility of the PDS with the power system. This involves assessing the impact of the PDS on the quality of the power supply network and vice versa. The standard provides guidelines for measuring and evaluating parameters such as current harmonic emissions, voltage fluctuations, and power factor. It also requires the PDS to comply with voltage fluctuation limits and harmonic current emission limits specified by other relevant standards.

Another important requirement is related to electromagnetic compatibility (EMC). The standard sets forth criteria to ensure that the operation of the PDS does not cause unacceptable electromagnetic disturbances that can interfere with the performance of other equipment connected to the same power supply network. This includes measures to control conducted and radiated emissions as well as immunity to external electromagnetic disturbances.

Benefits and Applications

Compliance with BS EN 61800-7-4:2018 offers several benefits. Firstly, it helps manufacturers design and produce PDS that meet the necessary quality and safety standards, resulting in reliable and efficient products. Secondly, adherence to this standard ensures interoperability between different PDS and power supply networks, allowing for seamless integration and operation. Furthermore, it helps in reducing power losses and minimizing environmental impact by optimizing power consumption and improving the overall efficiency of the system.

The applications of BS EN 61800-7-4:2018 are vast, covering various fields such as industrial automation, transportation, renewable energy, and HVAC systems. Adjustable speed drives play a crucial role in controlling motor speed, enabling precise control and significant energy savings. With the increasing demand for energy-efficient solutions, compliance with this standard becomes essential to ensure the reliable and safe operation of PDS in different applications.

Conclusion

BS EN 61800-7-4:2018 is a comprehensive technical standard that establishes the requirements and recommendations for adjustable speed electrical power drive systems. Compliance with this standard ensures compatibility with the power supply network, enhances interoperability, and improves the overall performance and efficiency of the system. By adhering to this standard, manufacturers can produce reliable and efficient products while end-users can benefit from energy savings and reduced environmental impact. Ultimately, BS EN 61800-7-4:2018 contributes to the advancement of technology and the promotion of sustainable practices in various industries.
