Functions:

1) The instrument uses a complex current method to measure capacitance, dielectric loss and other parameters. The test results are highly accurate and easy to automate measurements.

2) The instrument adopts frequency conversion technology to eliminate on-site 50Hz power frequency interference, 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 the Chinese character menu prompt.

4) The instrument is easy to operate, and the measurement process is controlled by the microprocessor. As long as the appropriate measurement method is selected, the measurement of the data can be automatically performed under the control of the microprocessor.

5) Integrated model with standard capacitor and high voltage power supply for on-site testing and field wiring reduction.

6) The instrument has high measurement accuracy and can meet the oil dielectric loss measurement requirements. Therefore, only the standard oil cup and the special test line can be used to measure the oil dielectric loss.

7) Set CVT test function, can realize CVT self-excitation test, no need external accessories, only in one test , C1, C2 capacitance and dielectric loss are all measured.

8) Reverse wiring test adopts ivddv technology, which eliminates the instability of the reverse wiring data.

9) With reverse wiring low-voltage shielding function, in the case of 220kVCVT busbar grounding, C11 can be used for 10kV reverse wiring dielectric loss measurement without disconnection

10) With the function of measuring high voltage dielectric loss, it can conduct dielectric loss test with voltage exceeding 10kV using high voltage transformer or series resonance.

11) Grounding protection function, when the instrument is not grounded or the grounding is poor, the instrument does not enter the normal program and does not output high voltage. Overcurrent protection function, the instrument is not damaged when the sample is shorted or broken down.

12) Electrical protection function, when the instrument operator accidentally touches the electric power, the instrument will cut off the high voltage immediately to ensure the safety of the test personnel.
