High voltage Frequency conversion/Different frequency anti-interference dielectric loss tester
KD600B dielectric loss tester is a high-precision instrument that can automatically measure the dielectric loss tangent value and capacitance of various high-voltage power equipment in power plants and substations.
Performance characteristics
1. With CVT self-excitation test, one-time wiring, while measuring C1, C2 capacitance and tgδ.
2. The maximum output voltage is 10kV, the maximum output current is 200mA, and the input current of the high-voltage dielectric loss test is increased to 5A.
3. With low voltage shielding function of reverse wiring, C11 can be measured 10kV reverse wiring dielectric loss without removing the wire when the CVT bus is grounded.
4. With positive/reverse wiring, internal/external standard capacitance, internal/external high voltage, various working modes, can do a variety of conventional dielectric loss tests, without external auxiliary equipment.
5. It has the measurement function of external voltage and external CN.
6. The instrument has high measurement accuracy and can meet the requirements of oil dielectric loss measurement, so it only needs to be equipped with standard oil cups and special test lines to achieve oil dielectric loss measurement.
7. Using frequency conversion technology to eliminate 50Hz power frequency interference on site, reliable data can be measured even in the environment of strong electromagnetic interference.
8. Grounding protection function, when the instrument is not grounded or poorly grounded, the instrument does not enter the normal procedure and does not output high voltage.
9. 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 is not damaged.
10. Can automatically distinguish capacitance, inductance, resistance type test.
11. Automatically identify the 50Hz / 60Hz system power supply.
12. Double power input with 110V/220V automatic identification can be provided to facilitate the use of foreign aid projects.
13. Automatically identify the 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.
14. With frequency conversion CVT self-excitation measurement interface, you can set high voltage/current, low voltage/current 4 protection limits to ensure personal and equipment safety.
15.CVT self-excitation measurement, C1/C2 can be measured at the same time, automatically compensate the busbar grounding and standard capacitor voltage distribution impact, no need to change the line and external accessories.
16. With CVT variable ratio measurement function. CVT ratio, polarity and phase errors can be measured.
17. The wiring contact is poor, the instrument has a prompt function, which is convenient for users to judge the measurement results and check the wiring error.
18. With thermal printer can print out, convenient for users to produce test reports.
19. With calendar clock, can store 100 groups of measurement data.
20. Standard capacitance and high voltage power supply are included to facilitate field testing and reduce field wiring.
21. The instrument adopts large-screen LCD LCD display, and the test process is prompted by the Chinese graphic menu.
