What are the technologies of dielectric loss tan delta tester?

Now the application field of automatic anti-interference dielectric loss tester is very wide, which is mainly used in on-site anti-interference dielectric loss measurement, or precision dielectric loss measurement in laboratories. So what are the technologies of the automatic anti-interference dielectric loss tester Tan Delta Tester?

The automatic anti-interference dielectric loss tester Tan Delta Tester adopts frequency conversion anti-interference and Fourier transform digital filtering technology, fully automatic intelligent measurement, and the measurement data is very stable under strong interference. The data acquisition circuit all adopts high-voltage stable devices, the acquisition board and the acquisition computer are shielded by the iron box float, and the instrument shell is grounded and shielded; In addition, anti-interference technologies such as light guide data, floating ground, large area, single point, digital filtering are used, and the computer processes the data of hundreds of power grid cycles to make the measurement results stable and reliable.

Automatic anti-interference dielectric loss tester Tan Delta Tester functional features:
1. Frequency conversion anti-interference Using frequency conversion anti-interference technology, it can still be accurately measured under 200% interference, and the test data is stable, which is suitable for anti-interference displacement test on site.
2. Good compatibility Automatically identify 50Hz/60Hz system power supply, support generator power supply, even if the frequency fluctuates greatly, it can be measured normally. Built-in series and parallel displacement measurement models, which are fully compatible with the calibration bench and dissipation standard, which is convenient for instrument cal
3. High-precision measurement Using frequency floating, digital waveform analysis and bridge self-calibration and other technologies, with high-precision three-terminal standard capacitors, high-precision dielectric loss measurement is realized, and the accuracy and stability of forward/reverse wiring measurement are consistent.
The input resistance of all ranges of the instrument is less than 2Ω, eliminating the effect of additional capacitance on the test line.
External oil cup can be connected to do precision insulating oil dielectric loss test, and external solid material measuring electrode can be connected to do precision insulation material dielectric loss test.
