What is IEC 60130-2-2020?

IEC 60130-2-2020 is an international standard that outlines the technical requirements for safety isolating and separating transformers in electrical installations. Published by the International Electrotechnical Commission (IEC), this standard provides guidelines for the design, testing, and performance of these transformers to ensure safe and reliable operation.

Key Technical Requirements

The IEC 60130-2-2020 standard specifies various technical requirements that safety isolating and separating transformers must meet. These requirements include voltage rating, insulation materials, protection against electric shock, temperature rise limits, and marking. Let's take a closer look at some of these key requirements.

Voltage Rating and Insulation Materials

One of the fundamental aspects addressed by the IEC 60130-2-2020 standard is the voltage rating of safety isolating and separating transformers. This standard ensures that transformers are designed and tested to withstand the specified voltage levels without any breakdown or insulation failure. Additionally, the insulation materials used in these transformers must also comply with certain specifications to ensure adequate electrical and thermal insulation properties.

Protection Against Electric Shock

Safety is a primary concern when it comes to electrical installations, and the IEC 60130-2-2020 standard places significant emphasis on protecting against electric shock. Transformers conforming to this standard must incorporate measures such as double insulation and reinforced insulation to ensure that users are protected from any potential harm caused by electrical shocks. Various tests, including dielectric strength and leakage current measurements, are conducted to verify the effectiveness of these protective measures.

Temperature Rise Limits and Marking

To prevent overheating and ensure system reliability, the IEC 60130-2-2020 standard defines maximum temperature rise limits for safety isolating and separating transformers. Excessive heat can degrade insulation materials and lead to premature failures. By specifying temperature rise limits, this standard ensures that transformers operate within safe temperature ranges, preventing any hazards and prolonging their lifespan. Additionally, transformers complying with this standard must be properly marked to indicate key specifications such as voltage rating, manufacturer information, and compliance with relevant regulations.

In Conclusion

The IEC 60130-2-2020 standard plays a crucial role in ensuring the safety and performance of safety isolating and separating transformers in electrical installations. By outlining technical requirements related to voltage rating, insulation materials, protection against electric shock, temperature rise limits, and marking, this standard promotes the use of reliable and compliant transformers. Adhering to these guidelines helps prevent accidents, protects users from electric shocks, and contributes to the overall efficiency and effectiveness of electrical systems.
