Series resonance Hertz power is a guide for you: the frequency response method test method of transformer winding deformation tester, transformer winding deformation tester is used to test transformer winding deformation of 6kV and above voltage level power transformers and other special purposes, power transformers are running or transported The process will inevitably be impacted by various fault short-circuit currents or physical impacts. Under the strong power generated by the short-circuit current, the transformer windings may lose stability, resulting in permanent deformation such as local deformation, bulging or displacement, which seriously affects the safety of the transformer run. The frequency response analysis method is used to measure the transformer winding deformation.

1. The environment and wiring confirmation of transformer winding deformation tester

1) The connection of the system fully meets the requirements of the winding connection mode; 2) Adjust the tap position of the transformer to achieve a large impedance (sub-tap); 3) There is no strong electromagnetic and contrast interference in the surrounding environment.

2. Login software of transformer winding deformation tester

Double-click the icon button of the transformer winding deformation tester. After the system flashes through the welcome interface, the system enters the test interface. At this time, if the device is not connected, the system will prompt

3. Input information of transformer winding deformation tester

If the transformer winding deformation tester is connected, you can enter the transformer information input interface. Enter or select the corresponding information in the corresponding text box, click the save button, and the system enters the test interface.

Fourth, the transformer winding deformation tester mode

1. Select scan mode of transformer winding deformation tester

Click "stop frequency" to select the stop frequency of the test. According to the set sweep parameters, the system will automatically set the parameters as the setting parameters. The parameters of the transformer winding deformation tester mainly include the start frequency, sweep mode and sweep point. If you need to adjust it, you can Click the corresponding parameter label in area A, and then automatically switch (when the mouse pointer moves). When the label can be changed, the label will automatically turn green.

2. Change the default information of the transformer winding deformation tester

If you want to re-adjust the default setting information, right-click the "Stop Frequency" button, the function menu will pop up, select "Mode Settings", and the information setting window will pop up, you can adjust the default scan information. After the adjustment is completed, restart the software and execute the test according to the adjusted default information.
