Characteristics
1) The instrument uses the complex current method to measure capacitance, dielectric loss and other parameters. The test result has high precision, which is convenient for automatic measurement.
2) The instrument adopts frequency conversion technology to eliminate 50Hz power frequency interference on site, and reliable data can be measured even in the environment of strong electromagnetic interference.
3) The instrument adopts a large-screen LCD display, and the test process is intuitive and easy to operate through English character menu prompts.
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 data measurement can be automatically completed under the control of the microprocessor.
5) Integrated model with standard capacitor and high voltage power supply, which is convenient for on-site testing and reduces on-site wiring.
6) The instrument has high measurement accuracy and can meet the requirements of oil dielectric loss measurement. Therefore, only a standard oil cup and a dedicated test line are needed to achieve oil dielectric loss measurement.
7) With CVT test function, it can realize CVT self-excitation method test, no external accessories are needed, only one measurement is required, and capacitance and dielectric loss of C1 and C2 are all measured.
8) The reverse wiring test adopts ivddv technology, which eliminates the phenomenon that the reverse wiring data is unstable in the past.
9) With reverse wiring low-voltage shielding function, in the case of 220kVCVT busbar grounding, C11 can be measured without disconnecting 10kV reverse wiring dielectric loss
10) It has the function of measuring high-voltage dielectric loss, and can use high-voltage transformers or series resonance to conduct dielectric loss tests over 10kV.
11) Ground protection function, when the instrument is not grounded or the ground is poor, the instrument does not enter the normal procedure and does not output high voltage. Overcurrent protection function, the instrument is not damaged when the test product is short-circuited or broken down.
12) Electric shock protection function, when the instrument operator accidentally gets an electric shock, the instrument will immediately cut off the high voltage to ensure the safety of the test personnel.
