Technical Analysis | Dry Type Transformer Partial Discharge Causes and Control Measures
IV. Partial Discharge Test of Dry Transformer 1.Waveform Analysis of Partial Discharge The voltage across the detection impedance Zm (that is, the detection signal) is quite small and must be amplified to give a distinct indication on the instrument. The peak value of th...Read more -
Technical Analysis | Dry Type Transformer Partial Discharge Causes and Control Measures
I.Cause of Partial Discharge The transformer insulator, metal body and so on are often with some sharp angle and burr, so the electric charges under the action of electric field intensity will concentrate in the sharp angle or burr position and result in partial discharg...Read more -

The second is that extremely fine particles dissolve in wa...Read more -
Major Problems and its Solutions Phase I- Processing of Stereoscopic Wound Cores for Distribution Transformers
A series of problems, such as larger diameter, the formation of waves on the cylinder, the deviation of the verticality of the assembly, and the unqualified performance after annealing during processing, are common problems in the stereoscopic wound core industry, especially for new companies. Th...Read more -
The Cooling Unit of Transformer
In the working process of transformer, a lot of heat will be produced, which seriously affects the performance of transformer. During the operation of transformer, the loss of winding and core will produce a lot of heat, which must be dissipated in time to avoid insulation damage caused by overh...Read more -
What is a transformer coil requirements in processing?
The coil of transformer is an important part of transformer. It is said that the heart of coil type transformer is very important to transformer. In the transformer, the coil is the part of the circuit. In the operation of the transformer, there will be some bad conditions such as over-voltage, h...Read more -
