Product features：

1 Tri-frequency transformer operation is simple and reliable

2 Can well meet the needs of transformer withstand voltage transformer

3. It is widely used in voltage transformer frequency multiplication induction withstand voltage test;

4. Carry out phase splitting and frequency doubling induction withstand voltage test on power transformers;

5. Perform frequency multiplication induction withstand voltage test on electrical products such as receiving induction coils.

6. By adjusting the induction quantity of the iron core gas change device, a large-capacity test product can be designed;

7. There is no transient overvoltage when the test product is broken down;

8. A wide range of applications, large field applications, and a large range of test product capabilities;

9. When the test product fails, the flowing lithium will automatically fall into the eyes due to the destruction of the temper, and short-circuit a small current through the fault point;

10. The support device can be used as a pressure test. Pressure devices and transformers sense the need for withstand voltage.

Q&A:

What should I do if the tri-frequency induction withstand voltage device has overcurrent or breakdown?

            1. The factory setting of the over-current protection we tested is 80% of the rated output current. When used for a small load, it should be re-adjusted according to the actual situation of the load;

            2. When over-current or breakdown occurs during the boost process, the industry adopts three-frequency induction withstand voltage, and the over-current protection action can protect the product under test and prevent the accident of the product under test from expanding. Cut off the input three-phase power to prevent damage to the three-frequency power generation device.
