1. Features CVT self-excitation testing, allowing simultaneous measurement of capacitance and tanδ of C1 and C2 with a single connection.

2. Features low-voltage and high-voltage shielding for reverse connection, enabling 10kV reverse connection dielectric 

loss measurement of C11 without disconnection when the CVT bus is grounded.

3. Features measurement functions for externally applied voltage and external CN.

4. Features CVT turns ratio measurement, meeting the needs of 35-500kV CVT devices.

5. Features multi-channel simultaneous measurement, allowing simultaneous testing of dielectric loss values for four test samples.

6. Features insulation resistance testing, capable of testing polarization index, absorption ratio, and insulation resistance.

7. Features automatic LCR measurement, capable of measuring inductance, capacitance, and resistance.

8. Employs frequency conversion technology to eliminate 50Hz power frequency interference in the field.

Reliable data can be obtained even in environments with strong electromagnetic interference.

9. Overcurrent protection function; the instrument is not damaged in the event of a short circuit or breakdown of the test sample.

10. Includes standard capacitors and a high-voltage power supply for easy on-site testing and reduced wiring.

11. The instrument features a large LCD screen, simple operation, and Chinese menu prompts throughout the testing process.

12. The instrument's function interface includes corresponding wiring diagrams, greatly simplifying wiring for the operator.

13. Equipped with Chinese/English language switching functionality.
