Special Transformer Ratio Group Tester

The HN6205T special transformer ratio group tester can automatically generate three-phase (120 °) or two-phase (90 °) power supplies with stable amplitude and constant phase. It has internal overcurrent protection function and high and low voltage reverse connection protection function. The test results are not affected by frequency and amplitude fluctuations of the power supply. The operation is very convenient, making it an ideal transformer ratio group polarity tester for power systems, transformer manufacturers, and railway electrical systems.

The HN205T special transformer ratio group tester is suitable for testing the ratio and phase difference of special transformers, as well as measuring rectifier transformers with phase shifting. Workflow: Input single-phase power supply, generate three-phase or two-phase power supply by internal power module, output to the high voltage side of the transformer, then sample both high and low voltage simultaneously, and finally calculate the group, transformation ratio, error, and phase difference.

Product features of transformer ratio tester

1. Specially suitable for testing the transformation ratio and phase difference of special transformers.

2. Especially suitable for measuring rectifier transformers with phase shifting, it intuitively displays the angle of phase shifting

3. Automatically generate three-phase (120 °) or two-phase (90 °) power sources with stable amplitude and constant phase.

4. Without being constrained by the internal wiring of the transformer, directly measure the voltage ratio and phase angle difference between the high and low voltage sides.

5. Real three-phase simultaneous measurement.

6. Test parameters are set in one go, and after converting the tap changer, they are directly tested to automatically determine the tap position and the standard transformation ratio after conversion.

7. Fast speed, the testing time for one set of data is 8 seconds.

8. The test results are not affected by fluctuations in the frequency and amplitude of the power supply.

9. Internally equipped with overcurrent protection function and protection function for high and low voltage reverse connection.

10. The entire testing process can be controlled by the upper computer, saving data and printing test reports.

11. The test results are automatically saved, with a maximum of 99 saved.

12. The instrument has a built-in user manual that can be accessed at any time.
