Introduction
1. The instrument adopts Fourier transform digital filtering technology to measure capacitance, dielectric loss and other parameters. The test results have high precision and are easy to realize automatic measurement.
2. The instrument adopts frequency conversion technology to eliminate 50Hz power frequency interference on site, and can measure reliable data even in the environment of strong electromagnetic interference.
3. Data storage: it is internally equipped with calendar chip and large capacity memory, which can save the test results at any time, view the historical records at any time, and print out.
4. Instrument data can be exported through USB flash disk.
5. Integrated model with standard capacitor and high voltage power supply, which is convenient for field test and reduces field wiring.
6. It has the function of reverse wiring low-voltage shielding. Under the condition of 220kV CVT bus grounding, the dielectric loss of C11 can be measured without disconnecting 10kV reverse wiring.
7. It can identify the frequency of external high-voltage power supply from 40Hz to 70Hz, and it is allowed to use power frequency power supply or series resonant power supply for large capacity and high-voltage dielectric loss test.
8. With CVT test function, it can realize CVT self excitation test, and can set four protection limits of high voltage / current and low voltage / current to ensure personal and equipment safety.
9. When testing CVT, it can not only automatically test the capacitance and dielectric loss of C1 and C2, but also test the total capacitance and dielectric loss of CVT equipment.
10. With a thermal printer.
11. With computer interface. One computer can control 32 instruments, which can be integrated into the comprehensive high voltage test vehicle to realize measurement, data processing and report output.
12. Grounding protection function, electric shock protection function.
