Product Description
I. Introduction
The structure and reference of the transformer is fixed after been made, Therefor, the frequency response of each winding will be almost the same normally.
Some case such as cut off between circles or phases in experience, cut off or winding moved for the pull of power in running, winding moved for hit in transportation, could change the reference of the transformer ,of which the frequency response will be changed, we could detect the deformation according to the frequency response curve.
Our company has designed the winding deformation tester base 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.

II. Features

Using the advanced technical of DDS;
2Using the high speed and advanced microprocessor to design;
3Using double channels of AD chip of 16 bits;
4With seven inch LCD touch screen of which the brightness can be adjusted;
5With thermal printer of which the print thick can be adjusted;
6It could store one hundred and twenty groups of data, which could be read to current screen or upload to the PC;
7With PC software using which we could upload data ,test, analyze data, print data, or create word document;
8Using USB2.0 to connect to the device;
9Tester dimension:31cm*15cm*5cm;
