HM5010 Winding Resistance Deformation Test Video
Product Overview
Even if a winding does not fail immediately after undergoing localized deformation, it may still harbor serious potential for future failure. If a transformer with a deformed winding continues to operate, it may fail due to overvoltage or short-circuit surges, and in some cases, it may even burn out spontaneously during operation. Therefore, the HM5010 Transformer Winding Deformation Tester was developed by Goldhome to meet on-site needs, drawing on similar products from both domestic and international markets while incorporating the specific requirements of China's power system. It features multi-channel waveform display and provides clear and concise test data.
Products Description
1. Features a built-in LCD screen, eliminating the need for an external laptop and making it easy to carry.
2. Runs on the Windows operating system, offering a more intuitive user interface and clear, at-a-glance data analysis.
3. Capable of continuously testing and displaying up to 9 curves.
4. Allows users to select any number of test curves and generate reports.
5. Offers strong resistance to interference and superior repeatability.

Parameter Settings:
1. Turn on the instrument's power switch; the instrument will boot into the Windows system. Double-click "Winding Deformation Tester" on the desktop to enter the test interface, as shown in Figure (1).
Figure (1)
2. On the test interface, click the "Settings" button to enter the parameter settings interface, as shown in Figure (2). After filling out the settings table, click "OK"; the instrument will automatically load the corresponding parameters.

3. After completing the parameter settings, select the corresponding winding (H-High Voltage Side, M-Medium Voltage Side, L-Low Voltage Side), excitation terminals (A, B, C, O), and response terminals (A, B, C, O). See Figure (3)
Figure (3)
4. After selecting the winding, excitation terminal, and response terminal, choose the test curve (Curve 1 is selected by default). Once the curve position is selected, press the "Start" button to begin the test. Upon completion, the instrument will display a save dialog box; click "OK" to complete the test process. (Note: Saved files will be organized into folders named according to the project unit, test location, and transformer model specified in the settings bar, with filenames consisting of the winding, excitation, response, and test time.)
To continue testing the next winding, check Curves 2 through 9 in sequence. All selected curves will be displayed simultaneously in the curve window in different colors for easy waveform comparison. After testing is complete, the "Data Analysis" table provides a clear overview of the standard deviation data for Curves 1–3, Curves 4–6, and Curves 7–9, along with winding status indicators in different colors. See Figure (IV)

6. Once all tests are complete, click the "Report" button to generate a test report. The report is in Word format.
7. To shut down the tester, first exit the software, then turn off the PC, and finally turn off the power switch.
