1. The instrument adopts complex current method to measure capacitance, dielectric loss and other parameters. The accuracy of the test results is high and it is easy to realize automatic measurement.
2. The instrument adopts frequency conversion technology to eliminate 50Hz I-frequency interference in the field, and can measure reliable data even in the environment of strong electromagnetic interference.
3. The instrument adopts large screen liquid crystal display, and the test process is intuitive and easy to operate through Chinese menu prompt.
4. The instrument is easy to operate and the measurement process is controlled by a microprocessor. As long as a proper measurement method is selected, the measurement of data can be automatically completed under the control of a microprocessor.
5. integrated model, with standard capacitance and high voltage power supply, easy to test on site and reduce field wiring.
6. The instrument has high measurement accuracy and can meet the requirements of oil dielectric loss measurement. Therefore, only standard oil cup and special test line are needed to realize oil dielectric loss measurement.
7. With CVT test function, the self excitation test of CVT can be realized without external accessories, only one-time measurement is needed, and the capacitance and dielectric loss of C1C2 are all measured.
8. ivddv technology is used in the reverse wiring test to eliminate the instability of the previous reverse wiring data.
9. It has the function of low-voltage shielding of reverse wiring. When the 220kV CVT bus is grounded, the dielectric loss measurement of 10kV reverse wiring can be carried out for C11 without disconnection
10. It has the function of measuring high-voltage dielectric loss, and can use high-voltage transformer or series resonance to carry out dielectric loss test of more than 10KV voltage.
12. Grounding protection function: when the instrument is not grounded or poorly grounded, the instrument will not enter the normal program and will not output high voltage. Over current protection function, the instrument will not be damaged in case of short circuit or breakdown of the test object.
13. Electric shock protection function: when the instrument operator accidentally gets electric shock, the instrument will cut off the high voltage immediately to ensure the safety of the tester
