Energy efficiency grades for dry transformers

The energy efficiency of dry-type transformer is a physical attribute of dry-type transformer, and the energy efficiency of dry-type transformer is the continuous embodiment of the capability of dry-type transformer, which is also an important way for dry-type transformer to play its role. The energy efficiency of dry type transformer can affect the efficiency of dry type transformer, so that the performance of dry type transformer is affected. So how to realize the energy efficiency of the dry transformer? How is it graded? Let's have a look together with the dry type transformer supplier of dry type transformer:

Dry-type Transformer

Grade 1 indicates that the energy saving of the product has reached the international advanced level and the lowest energy consumption; Level 2 indicates energy saving by product comparison; Level 3 indicates that the energy efficiency of the product is the average level of the Chinese market. Level 4 means the energy efficiency of the product is lower than the market average; Grade 5 is the market access index of products. Products lower than the requirements of this grade are not allowed to be produced and sold.

The energy efficiency index of grade A+ is 30% ~ 42%, that is, the measured power consumption under standard conditions is equivalent to 30% ~ 42% of the rated power consumption.

China has five energy efficiency levels for air conditioners, refrigerators and other products.

More than 100 countries have energy efficiency labeling systems in place. It is a color logo with a blue and white background. It is divided into 5 grades: 1, 2, 3, 4 and 5. Level 2 indicates energy saving; Level 3 indicates that the energy efficiency of the product is the average level of the Chinese market. Level 4 means the energy efficiency of the product is lower than the market average; Level 5 is the market access index. Products below this level are not allowed to be produced and sold.

The classification of energy efficiency of three phase dry type transformer is the main sign of dry transformer and also a variety of problems that need to be paid attention to in the process of dry transformer work. If you have any different problems about the energy efficiency of dry transformer, please pay attention to our manufacturers or communicate with our technicians.
