IEC & ANSI Standards
IEC and ANSI standards
Transformer design and manufacturing follow international standards that ensure safety, reliability and compatibility.
| Standard | Description |
|---|---|
| IEC 60076-1 | Power transformers — General |
| IEC 60076-2 | Temperature rise for liquid-immersed transformers |
| IEC 60076-3 | Insulation levels, dielectric tests and external clearances |
| IEC 60076-5 | Ability to withstand short-circuit |
| IEC 60076-6 | Reactors |
| IEC 60076-11 | Dry-type transformers |
The EU Ecodesign Regulation (EU) 2019/1783 sets minimum energy efficiency requirements for power transformers. BTB’s standard transformers comply with the Tier 2 requirements that entered into force on 1 July 2021.
