The KDZD3088 ultrasonic line local discharge inspection instrument independently developed and produced by our company uses precision high-frequency ultrasonic sensors to collect and select the characteristic sound waves emitted during partial discharge of 110kV and below power equipment, and realize the location and judgment of defects by filtering and comparing. And the real-time data collected can be synchronized to the cloud to truly realize front-end detection, and then view and analyze.

(1) High sensitivity, ergonomic design, friendly operation interface; Strong anti-interference ability, stable and reliable;

(2) Configure the laser aiming and positioning function to achieve accurate positioning of the fault point.
(3) Support low-speed vehicle inspection, speed ≤30km/h.
(4) With discharge amplitude, spectrum display function.
(5) The instrument supports real-time communication with mobile phones and tablets, and can synchronize real-time data collected to the cloud, truly realizing front-end detection and rear view analysis.
