Transformer Testing Technical Support

The article will focus on other necessary tests about transformer, such as AC withstand Voltage Test, Insulation dielectric performance test, Winding DC resistance measurement, CVT and so on.

This article will describe the necessary tests for transformers, focusing on insulation resistance measurement, dielectric loss factor and capacitance measurement, and partial discharge testing.

This article will focuses on some relative questions about Tan Delta Testing. It aims to help you know more deeply about TD Test.

This article will focus on the CT and VT testing procedure, and will also describe some specific operational details.

This article focuses on DC impedance and AC impedance, and will answer people's questions about these two impedances.

This article focuses on the IEC standard for the tan delta test, and will introduce the meaning of IEC 60851-5.

This article focuses on how to calculate the no-load loss of the transformer, helping you understand the no-load loss more directly.

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.
