The HYJF-2000 dual-channel digital partial discharge detection system is a major test item for insulation of power equipment, and parameters such as partial discharge quantity are important indicators for evaluating the quality of power equipment. The JFD-2000A partial discharge detection system, developed based on the latest international and domestic technological advancements, is a new generation member of the successful HTJF series partial discharge instruments. In addition to inheriting the advantages of the previous generation, this product also features full program-controlled automatic calibration, automatic synchronization, automatic voltage recording, automatic measurement saving and playback, and can measure various partial discharge parameters specified by IEC-270, such as discharge repetition rate n, average discharge current I, and square rate D. It adopts multiple view display modes such as sinusoidal and dot matrix, and new digital filtering and interference suppression functions, combined with rich dynamic statistical analysis patterns, enabling more effective suppression of on-site interference and making user operation and diagnosis more convenient and effortless. With continuous software development, its functions are also expanding, 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 Measurements" standards in terms of detection methods, measurement circuits, and technical performance parameters. It is suitable for partial discharge measurement of various high-voltage electrical equipment, covering all voltage and capacity levels, representing the advanced technology of domestic digital partial discharge instruments.
