Analysis of Winding Deformation of Power Transformer by Freq

ZC-206A transformer winding deformation tester, based on the measurement of characteristic parameters of transformer internal windings, adopts the method of internal fault frequency response analysis (FRA), which is being developed and perfected by developed countries in the world, can accurately judge transformer internal faults.

 

 

 

After the design and manufacture of transformer, its coil and internal structure are determined. Therefore, for a multi-winding transformer coil, if the voltage level is the same and the winding method is the same, the corresponding parameters (Ci, Li) of each coil should be determined. Therefore, the frequency domain characteristic response of each coil is determined, and the frequency spectrum of the corresponding three-phase coils is comparable.

 

 

 

Transformer is an indispensable and important instrument in power system. It may cause transformer winding deformation during transformer maintenance or transportation. At the same time, the transformer may also occur inter-turn and inter-phase short circuit during the test process. Transformer winding deformation tester is a set of power equipment which plays a decisive role in the process of domestic power infrastructure construction. It plays a key supporting role in our country’s power transmission.

 

 

 

Transformer winding deformation tester is mainly used to measure the parameters of transformer internal winding. After obtaining all kinds of accurate measurement data, the computer system carries out comparative analysis to judge the internal fault state of transformer.
