- Scope
- This standard specifies the energy efficiency grades, limit values of energy efficiency, evaluation values of energy conservation and test methods for three-phase distribution transformers. This standard is applicable to oil-immersed distribution transformers with three-phase 10 kV voltage level, non-excitation voltage regulation, rated capacity 30 kVA~1600 kVA and dry-type distribution transformers rated capacity 30 kVA~2500 kVA. This standard does not apply to gas-filled transformers.
