CYDL-124 digital partial discharge detector is the newly development digital partial discharge testing machine. It adopts 32 bits high performance singlechip circuit, combining touching-screen operation, improve the service life of the instrument. The instrument can be automatically corrected by one button, detecting sensitively, wide dynamic amplifier system, anti-interference strongly.
