Automatic anti-interference dielectric loss testerZC-221J

1. The instrument adopts Fourier transform digital filtering technology to measure capacitance, dielectric loss and other parameters. The test result has high precision and is convenient to realize automatic measurement.
2. The instrument adopts frequency conversion technology to eliminate 50Hz power frequency interference on the spot. Reliable test results can be obtained even under strong electromagnetic interference.
3. Adopt full-touch large LCD, simple operation. Large full graphic interface, every processes are very clear, operators can use it without any additional professional training. The whole processes can be operated with the touch screen.
4. Data storage: equipped with calendar chip and mass memory, it can save the test results at any time, view the history record at any time, and print out. Current time and storage time can be displayed and printed at any time
5. Scientific and advanced data management: instrument data can be exported through U disk, and can be viewed and managed by special software on any PC.
6. 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 done automatically under the control of the microprocessor.
7. Integrated body, Standard capacitance and high voltage power supply are included to facilitate field test and reduce field wiring
8, the instrument measurement accuracy is high, can meet the requirements of oil dielectric loss measurement, so only need to be equipped with a standard oil cup, and special test line to achieve oil dielectric loss measurement.
9. Grounding, 10kV negative wiring dielectric loss measurement can be carried out for C11 without disconnection
10. Able to do ac withstand test. Convenient to do ac withstand voltage test with PT CT secondary , Convenient to do the withstand voltage test with 400V low voltage system.
11. Able to identify the frequency of external high-voltage power supply from 40Hz to 70Hz, and allow the labor frequency power supply or serial resonant power supply to conduct large-capacity and high-voltage dielectric loss test.
12. With CVT test function, self-excitation test of CVT can be realized, and 4 protection limits of high voltage/current and low voltage/current can be set to ensure personal and equipment safety.
13. When testing CVT, it can not only automatically test the capacitance and dielectric loss of C1 and C2, but also can test the total capacitance and dielectric loss of CVT equipment
14, Equipped with a thermal printer, a calendar clock and U disk output port.
15, with computer interface.One computer can control 32 instruments, which can be integrated into the integrated high-voltage test vehicle to realize measurement, data processing and report output.
16. Grounding protection function. When the instrument is ungrounded or poorly grounded, the instrument will not enter the normal procedure and will not output high voltage. Over current protection function, instrument will not be damaged when testing a short circuit or breakdown sample.
17. Electric shock protection function, When the instrument operator accidentally gets an electric shock, the instrument will cut off the high voltage immediately to ensure the safety of the test personnel.
