IEC standards
- IEC 60076-1: It is a general requirement standard for transformers. It stipulates the basic design principles, performance requirements, test methods, etc. of transformers. It is the basis for other transformer standards.
- IEC 60076-2: Applicable to liquid-immersed power transformers. It clarifies the requirements for the design, manufacturing, testing and performance of liquid-immersed transformers, including specific requirements for different types and rated power transformers.
- IEC 60076-3: For dry-type power transformers, it specifies the design, manufacturing, testing and performance requirements for dry-type power transformers in detail, covering the specific requirements for dry-type transformers of different types and rated power.
- IEC 60076-4: Focuses on test methods for transformers, describing in detail the methods and procedures for conducting various tests on transformers to ensure that the transformer complies with relevant performance and safety standards.
IEEE standards
In the United States, the American National Standards Institute (ANSI) and the Institute of Electrical and Electronics Engineers (IEEE) have jointly developed a series of transformer standards covering design, testing, performance and other aspects to ensure the interoperability and reliability of transformers in the US power grid. , such as IEEE C57.12.00, etc., stipulates the general requirements and test procedures for power transformers.
EN standards
Transformers in the EU are required to comply with EN (European Standards). These standards are formulated by the European Committee for Electrotechnical Standardization (CENELEC) to ensure the consistency of transformer design, safety and performance among EU member states, and promote interoperability and regulations among member states. Compliance, such as the EN 60076 series of standards, is widely used in the European Union and has a certain correspondence and coordination with the IEC 60076 series of standards.
