GHJF-9302 Intelligent Partial Discharge Detector
1、 Overview

The GHJF-9302 intelligent partial discharge detector is a new generation of digital intelligent instrument launched by our company to the market. Based on the original products JF-9300 and JF-9301 partial discharge detectors, the instrument adopts an embedded ARM system as the central processing unit, controls a 12 bit resolution high-speed analog-to-digital conversion chip for data acquisition, and stores the collected data in dual port RAM.

Realize the transition from analog to digital. Use a 260000 color high-resolution TFT-LCD digital LCD display module to display discharge pulse waveforms in real time, equipped with VGA interface, can be connected to an external display, can lock and analyze waveforms, and automatically generate and print test reports.

2、 Characteristics of GHJF-9302 Intelligent Partial Discharge Detector

1. Color display, dual color waveform display, clearer and more intuitive;
2. The waveform can be locked, making it easier to carefully examine the details of the discharge waveform;
3. Automatically measure and display the time base frequency of the test power supply, without the need for manual switching;
4. Equipped with VGA interface, it can be connected to large-sized displays externally;
5. Equipped with a micro printer that can directly generate printed test reports;
Compared to oscilloscope tubes, it has a longer lifespan.
