The intelligent partial discharge detector is the latest company to market a new generation of digital intelligent instruments, the instruments in their original product JF-2002, JF-2006 instrument based on ARM embedded system as a central processing unit, control of high speed 12-bit resolution analog-digital conversion chip for data collection, to store collected data in the dual-port RAM in. Make the leap from analog to digital. With 260,000 colors TFT-LCD with high resolution digital LCD module display discharge pulse waveforms in real time, equipped with VGA interface and an external monitor.
With conventional analog oscilloscope tubes display compared to the PD detector has the following characteristics:
1. color display, dual color displays waveforms, more clear and intuitive;
2. lock the waveform, easier to look carefully at the wave-shaped details;
3. automatic measurement and display of the test when the base frequencies without manual switching;
4. it is equipped with mini-printers, you can lock the waveform, print test reports;
5. equipped with VGA interface, external large-size display; This instrument detection high sensitivity, sample capacitance range, wide range of applicable test articles, enter (test impedance) equipped and band combinations (nine).
After proper calibration, the instrument can read-discharge pulse discharge.
This instrument is the electric power sector, manufacturers and research institutes such as the extensive use of partial discharge test equipment.
Main technical index:

3． the amplifier frequency bands:
（1）：Low-end: 10KHZ, 20KHZ ，40KHZ optional.
（2）：High-end: 80KHZ, 200KHZ ,300KHZ optional.
4. amplifier gain adjustment:
Rough six stalls, gain 20 ± 1dB; fine adjustment range ≥ 20dB.Data for 10 times between each document: third test data for 98, the second document shows data for 9.8, in third gear more than 120 test data, to detect data shall be transferred to the second document, and therefore the data should be multiplied by 10 for actual measurements.
5. Time window:
（1）：Window width: adjustable range 15 °-175 °;
（2）：Window position: each pane can be rotated 0 °-180 °;
（3）：Two time Windows can be open or open, respectively.
6. discharge scale:
0-100 error < ± 3%
7. Oval Base:
( 1)： Frequency: 50HZ, or external power supplies synchronized (as often)
（2）：Elliptic rotation: To 30 ° for a document, can be used for 360 ° rotation.
（3）：Display mode: oval-line
8. Test voltage meter: compression ratio can be set!Accuracy: better than ± 3%
9. You can carefully lock the waveform analysis, locked you can directly print test report
10. Channel switching can be a, b, c according to the test requirements of the three channel switch
11. This machine is equipped with clock display, you can record test date: year, month, day
12. Dimensions: 320x480x190 (width x depth x height) mm3
