According to relevant national standards, such as GB 20052-2020 “Energy Efficiency Limits and Grades for Power Transformers”, the energy efficiency grades of transformers are divided based on indicators such as no-load loss and load loss. Specifically, by measuring and calculating the no-load losses (losses in the iron core of transformers under no-load conditions, mainly related to the iron core material, magnetic flux density, etc.) and load losses (losses caused by resistance and stray losses caused by leakage flux in the winding when the transformer is running under load) of transformers with different capacities and voltage levels, and comparing them with the corresponding values specified in the standard, the energy efficiency level can be determined.
Energy consumption level: Transformers with third level energy efficiency are at a relatively moderate level in terms of energy consumption. Compared with first level energy efficiency, its no-load and load losses are relatively high, but it is more energy-efficient than products with lower energy efficiency levels. Taking three-phase distribution transformers of 10kV and below as an example, the allowable values of no-load loss and load loss for third level energy efficiency will be slightly higher than those for first level energy efficiency, but still meet the basic requirements of the country for energy-saving products.
Efficiency performance: In actual operation, the efficiency of a three-level energy-efficient transformer can be maintained at a reasonable level within a certain load range. Generally speaking, under typical load conditions, its efficiency may be around 95% -98%, and the specific values may vary depending on the specific specifications and operating conditions of the transformer.
Market access and application: Level 3 energy efficiency is one of the basic thresholds for transformers to enter the market. Many engineering projects and power systems consider Level 3 energy efficiency as a basic optional standard when selecting transformers. In some scenarios where energy-saving requirements are not particularly high or budgets are relatively limited, three-level energy efficiency transformers have certain market competitiveness and can be widely used in general industrial, commercial, and residential power supply places.
Energy conservation and environmental protection: Although the energy-saving effect of three-level energy efficiency transformers is not as good as that of first – and second level energy efficiency products, the extensive use of three-level energy efficiency transformers can still reduce the energy consumption of the power system to a certain extent, reduce energy waste and corresponding greenhouse gas emissions such as carbon dioxide, compared to the use of older models with lower energy efficiency. This has positive significance for promoting energy conservation and emission reduction work in the whole society.
