Test process and precautions for using transformer winding deformation tester

1.  First check whether the transformer is in good grounding condition, and all bushing leads should be untied.   

2.  Record in detail the nameplate data of the test product and whether there are any abnormalities in the original working conditions, as well as the tap position of the test product transformer under the current test conditions, and carefully enter the test product situation registration window.   

3.  According to the situation of the test product, a subdirectory of the test product data file should be established in the transformer winding deformation tester; after the test is completed, the measured data should be backed up to this directory, and attention should be paid to sorting. 
 
4.  Data storage format, the files generated by the transformer winding deformation tester are stored in the form of ASCII code, and users can read and modify them with various text editing software.   

5.  The transformer winding deformation tester measures the transformer that has just been out of operation. Before measurement, it should be allowed to dissipate heat and cool down as much as possible; but during the entire measurement process, the cooling measures should be stopped to maintain the temperature, so as to avoid excessive temperature changes during the measurement process and affect the consistency of the measurement results.
