  key feature 

1. The main circuit switching output using a single tube,So that the asymmetry of the instrument itself is reduced to zero, With positive and negative test function, to improve the applicability of the instrument.
2. Using general purpose oscilloscope or computer control;Can preset the standard waveform of the measured motor. Can realize some functions about the work of the motor interturn test ,such as automatic switching, automatic analysis of the test, judgment, automatic storage of test parameters and test results, print and so on . It is convenient to save the test data.
3. When unqualified products, automatic discriminant and sound and light alarm and displayed on the display.
4. Technology is used in electric regulator, test mode, comparison area and the comparison of frequency.
5. Large energy output,especially suitable for the large capacity motor、Transformers、electric appliance and other low sense winding.
6. The instrument specifications (test accuracy) in the country is leading, reached the international similar product standards.
7. For the detection of single / three-phase DC motor, transformer, electrical coils，increase the scope of the instrument.SO the RZJ turn insulation tester is that the motor manufacturers and build units to improve product quality and reliability essential special detection equipment.

 security

1. High voltage circuit has to start, stop buttons and dual foot switch insurance circuit, the safety and reliability of the instrument operation is higher.
2. High voltage output circuit with high voltage display digital table, can display high-voltage equipment at work, In the digital table shows changes to "0", reminding the operator to swap the motor (coil), Avoid high-pressure switch motor(coil), increase the safety of use. At the same time with a warning  when  the instrument is working, light serve as a warning.
3. Output high voltage wires with 30 kv line of silicone pressure. Fixture with large size, and good elastic clamp,Make better contact with the motor and fixtures.

 Reliability

Thyratron, filament, and trigger of the transformer with low voltage work mode, greatly reduces the voltage of high voltage auxiliary power supply circuit and operating voltage of trigger transformer, improves the safety and reliability.

Using high voltage loop isolated high frequency current sensor, and directly display through the thyratron and winding current waveform, to prevent the damage caused by a thyratron overload, at the same time, reduce the interference on the oscilloscope.
