1. What is the PD detector
SXJF-21 PD detector is a new generation of digital intelligent instrument newly marketed by our company. Based on the original products JF-22 and JF-26 PD detectors, this instrument adopts embedded ARM system as the central processing unit, controls the high-speed A/D conversion chip with 12-bit resolution to collect data, and stores the collected data in dual-port RAM. Realize the leap from analog to digital. Using 26, color high-resolution TFT-LCD digital liquid crystal display module to display the discharge pulse waveform in real time, equipped with VGA interface, which can be connected to the display.

II. Performance characteristics of partial discharge tester
Compared with the traditional analog oscilloscope tube display partial discharge detector, it has the following characteristics:
1. Color display, double-color display waveform, more clear and intuitive;
2. The waveform can be locked, which is more convenient to carefully check the details of the discharge waveform;
3. automatically measure and display the time base frequency of the test power supply without manual switching;
4. Equipped with VGA interface, which can be connected to a large-size display;
5. Compared with oscilloscope tube, the service life is longer.
this instrument has high detection sensitivity, large sample capacitance coverage, wide applicable sample range, complete input unit (detection impedance) and many frequency band combinations (nine types). After proper calibration, the instrument can directly read the discharge amount of discharge pulse.
This instrument is widely used in electric power departments, manufacturers and scientific research units.
