Product Description

SFRA-III Motor Winding Deformation Test Set Transformer Short-Circuit Impedance Tester

Product Description

 

Normally, the structure and reference of the transformer are fixed after being made, therefore, the frequency response of each winding will be almost the same. However, under some special conditions, such as cut off between circles or phases during the test, cut off or winding moved during running, or winding moved in transportation, these conditions may change the structure of the transformer, then the frequency response may be changed, we could detect the deformation according to the frequency response curve.

Our company has designed the SFRA-III Motor Winding Deformation Test Set Transformer Short-Circuit Impedance Tester based on the idea and the advanced technique. It could draw the frequency response curve accurately. Then we compare the curves horizontally or vertically to detect the deformation of the transformer.

SFRA-III Motor Winding Deformation Test Set Transformer Short-Circuit Impedance Tester is a powerful and sensitive method to evaluate the core, winding, and clamping structures of power transformers, by measuring their electrical transfer functions over a wide frequency range.
