1. Self-excitation method test for CVT, one-time wiring, simultaneously measuring capacitance and tgδ of C1 and C2
2. Has the function of external applied voltage and external CN measurement
3. The instrument has high measurement accuracy and can meet the requirements of oil dielectric loss measurement. Therefore, only a standard oil cup and special test wires are needed to achieve oil dielectric loss measurement
4. Uses frequency conversion technology to eliminate on-site 50Hz power frequency interference, and can obtain reliable data even in strong electromagnetic interference environments
5. Grounding protection function: when the instrument is not grounded or poorly grounded, it will not enter the normal program and will not output high voltage
6. Overcurrent protection function: the instrument will not be damaged in case of short circuit or breakdown of the test object
7. Built-in standard capacitor and high-voltage power supply, convenient for on-site testing, reducing on-site wiring
8. The instrument adopts a large-screen LCD display, and the test process is intuitive and easy to operate through Chinese menu prompts
Dielectric loss insulation test can effectively detect overall moisture, deterioration, and local defects of electrical equipment insulation, and is widely used in electrical manufacturing, electrical equipment installation, handover, and preventive tests.
The anti-interference dielectric loss automatic tester adopts variable frequency power supply technology, using single-chip microcomputer and electronic technology for automatic frequency conversion, analog/digital conversion, and data calculation, achieving strong anti-interference ability, fast test speed, high accuracy, and simple operation.
The variable frequency power supply uses a high-power switching power supply, outputs 45Hz and 55Hz pure sine waves, automatically boosts voltage, and can provide up to 10kV voltage; automatically filters out 50Hz interference, suitable for on-site testing in substations and other places with large electromagnetic interference.
