Detailed introduction
The JF-A01D partial discharge detector is a new type of digital partial discharge detector developed by our company. It retains the advantages of the JF-A01N partial discharge detector, while reducing the size and optimizing performance. It uses a 10.1-inch touch screen to replace the traditional The operation mode of the oscilloscope and the physical knob makes it more convenient to use.
 
The instrument adopts full touch screen operation, which 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 communication to upload test data. The instrument has the characteristics of high detection sensitivity, wide range of applicable test products, large dynamic range of the amplification system, multiple combinations of frequency bands (nine types), and strong anti-interference ability. This instrument is used in conjunction with a calibration pulse generator and an input unit. It is a practical partial discharge test instrument widely used by power departments, manufacturers, and scientific research institutes.
