Several standards govern the design, manufacturing, testing, and maintenance of transformers. These standards ensure the reliability, safety, and performance of transformers in various applications. Here are some commonly recognized transformer standards:
- IEC 60076: This series of international standards, developed by the International Electrotechnical Commission (IEC), addresses power transformers. It includes standards such as IEC 60076-1 (General), IEC 60076-2 (Temperature Rise), IEC 60076-3 (Insulation Levels and Dielectric Tests), and IEC 60076-5 (Ability to Withstand Short Circuit).
- ANSI/IEEE C57: The American National Standards Institute (ANSI) and the Institute of Electrical and Electronics Engineers (IEEE) jointly develop standards for transformers. The C57 series includes standards such as ANSI/IEEE C57.12 (Distribution Transformers), ANSI/IEEE C57.91 (Guide for Loading Mineral-Oil Immersed Transformers), and ANSI/IEEE C57.12.90 (Guide for Transformer Loss Measurement).
- CSA C88: Developed by the Canadian Standards Association (CSA), the CSA C88 standard covers power transformers, including requirements for design, testing, and performance.
- AS/NZS 60076: This standard, used in Australia and New Zealand, is based on IEC 60076 and provides guidelines for power transformers.
- GB/T 6451: This Chinese standard specifies the technical requirements for power transformers and includes aspects such as design, manufacturing, testing, and inspection.
- JIS C 1731: The Japanese Industrial Standards (JIS) includes JIS C 1731, which covers oil-immersed transformers and provides guidelines for their design, construction, and testing.
