Product Details

The dual-channel digital PD detection system is a key insulation test item，PD parameters are key indicators for evaluating power equipment quality. The JFD-2000A PD detection system, developed based on the latest international and domestic technological advances, is the new generation member of the successful HTJF series PD testers. In addition to inheriting the advantages of previous products, it features fully automatic calibration, auto synchronization, auto voltage recording, auto measurement save/playback, capable of measuring IEC-270 specified PD parameters such as discharge repetition rate n, average discharge current I, square rate D, etc. It offers sine, dot matrix and other display modes, new digital filtering and interference suppression, combined with rich dynamic statistical analysis spectra for more effective field interference suppression, making user operation and diagnosis simpler and more convenient. With continuous software development, its functions are expanding, including pulse polarity identification and balanced circuit PD measurement.

JFD-2000A fully complies with GB7354 and IEC-270 PD measurement standards. Suitable for PD measurement of all HV equipment.Its voltage and capacity ratings represent advanced domestic digital PD tester technology.
