The HYJF-2000 dual channel digital partial discharge detection system is the main test item for insulation of power equipment, and parameters such as partial discharge are important indicators for evaluating the quality of power equipment. The JFD-2000A partial discharge detection system, developed based on current international and domestic technological advancements, is a new generation member of the successful HTJF series partial discharge instrument. In addition to inheriting the advantages of the previous generation product, this product also has functions such as full process control, automatic calibration, automatic synchronization, automatic voltage recording, automatic measurement, storage and playback. It can measure various partial discharge parameters specified by IEC-270, such as discharge repetition rate n, average discharge current I, square rate D, etc. It adopts multiple view display modes such as sine and dot matrix, new digital filtering and interference suppression functions, combined with rich dynamic statistical analysis graphs, making on-site interference more effectively suppressed, and user operation and diagnosis more convenient and comfortable. With the continuous development of software, its functions continue to expand, such as pulse polarity discrimination and partial discharge measurement in balanced circuit mode.

The JFD-2000A partial discharge detection system fully complies with the new GB7354 and IEC-270 "Partial Discharge Measurement" standards in terms of its detection method, measurement circuit, and technical performance parameters. Suitable for partial discharge measurement of various high-voltage electrical equipment, covering full voltage and capacity levels, representing the advanced technology of digital partial discharge instruments in China.
