JJF 1261.20-2017 Rules of Metrology Testing for Energy Efficiency of Power Transformers

Scope

This standard applies to the energy efficiency measurement requirements, measurement and testing procedures, measurement and testing methods, evaluation criteria for measurement and testing results, and test reports of three-phase oil-immersed power transformers with a rated frequency of 50 Hz, a voltage rating of 35 kV to 220 kV, and a rated capacity of 3,150 kVA and above.
This standard applies to the supervision and testing of energy efficiency measurement of power transformers. Units that produce and sell power transformers can also refer to this standard for testing.
The power transformers accepted for testing should be products that have passed the manufacturer's self-inspection or goods imported and sold by sellers.
This standard does not apply to dry-type transformers, high-impedance transformers, and inflatable transformers.
