Transformer Testing Technical Support

Among the many maintenance methods, the DC resistance test is widely used in routine transformer inspection. As an effective detection method, the DC resistance test can help engineers find potential problems in time and ensure the reliability and safety of the equipment.

In the transformer DC resistance test, it will be found that the DC resistance value of the winding will be unbalanced, the reason can be divided into human factors, winding structure and material problems and transformer defects in three cases.

The impact tests in electrical engineering generally include operation impact test, lightning impact test and steep wave front impact test, the purpose of which is to test the insulation strength of electrical equipment.

This article elaborates on the composition, calculation method and related factors of transformer loss. Iron loss and copper loss are fixed loss and variable loss of transformer respectively. The article gives the calculation formulas of active loss, reactive loss and comprehensive power loss, as well as the selection conditions of each parameter. Then, the characteristics of transformer loss are discussed, including the composition and influencing factors of no-load loss and load loss.

Transformers convert AC voltage using electromagnetic induction, essential for power transmission and distribution. They adjust voltage to suit different applications, with the primary coil generating a magnetic field that induces force in the secondary coil. The coil turn ratio determines the voltage conversion.
