JJF 1261.20-2015 Rules of Metrology Testing for Energy Efficiency of Power Transformers

Scope

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