Overview

HZJF-9011D partial discharge detector is a new type of digital partial discharge detector developed by our company. It retains the advantages of HZJF-9011 partial discharge detector, and at the same time reduces the size and further optimizes performance. The 10.1-inch touch screen replaces the traditional The operation mode of the oscilloscope tube plus physical knob makes it more complete in function, more convenient to use and more reliable in performance.

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