What is EN 61558-2-16:2020?


The field of electrical engineering encompasses a wide range of products, systems, and standards. One such standard that plays a vital role in ensuring the safety and performance of electrical equipment is EN 61558-2-16:2020. In this article, we will explore what this standard entails and why it is important for professionals in the industry.

Understanding EN 61558-2-16:2020

EN 61558-2-16:2020 is a European standard that specifically focuses on safety requirements for transformers, power supply units, reactors, and similar devices used in electrical installations. It covers aspects such as insulation, protection against electric shock, thermal performance, and mechanical strength. The purpose of this standard is to ensure that these devices have appropriate safety measures in place to prevent accidents, fire hazards, and other potential risks associated with electrical equipment.

Key Features and Updates

EN 61558-2-16:2020 introduces several significant updates compared to its previous versions. One notable change is the inclusion of stricter requirements for temperature rise limits during overload conditions. This ensures that transformer cores and windings do not exceed safe operating temperatures, thus mitigating the risk of failures or malfunctions. Additionally, the standard now incorporates updated test methods and criteria to evaluate electrical insulation and withstand voltage capabilities. These amendments reflect the advancements in technology and address new challenges faced by the electrical engineering industry.

Another important aspect of EN 61558-2-16:2020 is its compatibility with other standards. It aligns with the Low Voltage Directive (LVD) and the Electromagnetic Compatibility (EMC) Directive, making it easier for manufacturers to comply with multiple regulations simultaneously. This harmonization simplifies the process of ensuring safety and quality while reducing the complexity of conformity assessment procedures. It also facilitates the free movement of compliant products within the European market.

Compliance and Implications

Compliance with EN 61558-2-16:2020 is crucial for manufacturers, installers, and maintenance personnel involved in the electrical engineering industry. Adhering to this standard not only ensures the safety of end-users but also protects the reputation and credibility of businesses. Non-compliance can lead to severe consequences, including legal liabilities, product recalls, and damage to brand image. Therefore, it is essential for professionals to stay up-to-date with the latest version of the standard and incorporate its requirements into their design, manufacturing, and testing processes.

In conclusion, EN 61558-2-16:2020 is an important technical standard that establishes safety requirements for transformers, power supply units, reactors, and similar devices used in electrical installations. Its comprehensive provisions address various aspects of safety, thermal performance, and mechanical strength. By adhering to this standard, professionals in the electrical engineering industry can ensure the production of safe, reliable, and high-quality equipment, thereby safeguarding both users and businesses.
