Audited Supplier Portable automatic DC high voltage frequency conversion and abnormal frequency anti-interference dielectric loss tester device
Performance Characteristics
1. It has the function of measuring external voltage and external CN.
2. The instrument has high measurement accuracy and can meet the requirements of oil dielectric loss measurement. Therefore, it only needs to be equipped with standard oil cup and special test line to realize oil dielectric loss measurement.
3. Frequency conversion technology is used to eliminate 50Hz power frequency interference in the field, and reliable data can be measured even in the environment of strong electromagnetic interference.
4. Ground protection function, when the instrument does not ground wire or poor ground, the instrument does not enter the normal program, do not output high voltage.
5. With over current, over voltage and ground protection and other multi-level protection, safe and reliable in the test short circuit or breakdown of the instrument will not be damaged.
6. Over-current protection function, in the sample short circuit or breakdown of the instrument will not be damaged.
7. Standard capacitor and high voltage power supply are attached to facilitate field testing and reduce field wiring.
8. Can automatically distinguish capacitance, inductance, resistance type test.
9. Automatic identification of 50Hz / 60Hz system working power supply.
10. It can provide dual power input of 110V/220V automatic identification to facilitate the use of foreign aid projects.
11. Automatic identification of external high voltage power supply frequency 40Hz ~ 70Hz, allowing the use of power frequency power supply or series resonant power supply to do large capacity high voltage dielectric loss test.
12. The wiring contact is bad, the instrument has the prompt function, which is convenient for users to judge the measurement results and check the wiring errors.
13. With thermal printer can print output, convenient for users out of the test report.
14. With calendar clock, it can store 100 groups of measurement data.
15. The instrument adopts large-screen LCD display, and the test process is prompted by Chinese graphic menu.
