Product Description
JYC Full Automatic Frequency Conversion Anti-interference Dielectric Loss Tester
It is used for on-site anti-interference dielectric loss measurement or laboratory precise dielectric loss measurement. The instrument is an integrated structure, built in dielectric loss bridge, frequency conversion power supply, test transformer and standard capacitor. Adopting the frequency conversion anti-interference and Fourier transform digital filtering technology, with the full automatic intelligent test, the measured data is very stable under strong interference. The measurement results are displayed on large screen LCD and output by printing.
Function Introduction
1..With positive and negative connection, internal/external standard capacitance, internal and external high voltage various working modes, integrated structure, can do various conventional dielectric loss tests without any auxiliary equipment.
2..With LCD screen, menu operation, abundant test data, distinguishing capacitance, inductance, resistance type tested products automatically, and print output.
3..With the interface to connect external standard capacitor, the external oil cup to do the precision insulating oil dielectric loss test, the external solid material measuring electrode to do the dielectric loss test of the precision insulating material, and the high voltage standard capacitor to do high voltage dielectric loss test.
4..Automatically identify the power supply of the 50Hz/60Hz system, and support the power supply of the generator. It can also measure normally even if the frequency fluctuates.
5..with built-in series and parallel measurement models for facilitating calibration of instrument.
CVT self excitation frequency conversion measurement interface, C1/C2 can be measured simultaneously by one time of wiring, automatic compensation of the bus grounding and voltage dividing of the standard capacitor , without changing the cable and connecting with any accessories, self excited high voltage connection cable can be on the ground.
6..With the function of reverse wiring low voltage shielding, C11 can be used to measure the dielectric loss of 10kV without reverse wiring, if the 220kV CVT bus is grounded.
7..Automatically identifying of external high voltage test power with frequency from 40Hz to 70Hz, it can support power frequency power, conversion frequency power and series resonant power to be the power source for large capacity and high voltage dielectric loss test.
8..With calendar clock and computer interface, storage for 100 sets of measurement data.
