ZXJF-2002 High Voltage Test Kit /High Voltage Partial Discharge Detector

ZXJF-2002 Partial Discharge Detector /PD Detector

Product brief introduction :

ZXJF-2002 partial discharge detector is a new type of analog partial discharge detector developed by our company. It retains the advantages of its predecessor, while reducing the size, and further optimizing the performance, making it more complete, more convenient to use, and more efficient. reliable.

The PD Detector uses 32 high-performance single-chip circuits, combined with the digital pulse potentiometer knob, which not only improves the service life of the operation, but also adds the following functions: one-button automatic calibration; high voltage test voltage divider ratio can be set; serial communication upload test data. The instrument has the characteristics of high detection sensitivity, wide range of applicable test samples, large dynamic range of the amplification system, multiple frequency band combinations (nine types), and strong anti-interference ability. This instrument is used in conjunction with the calibration pulse generator and input unit, and is a practical partial discharge test instrument widely used by power departments, manufacturers and scientific research institutes.
