KDZD Portable partial discharge tester detector
Product Introduction
High sensitivity: amplifier system dynamic range; The test range is wide and the operation is simple
Strong anti-interference ability: anti-interference components and gate display circuit
It has four kinds of high frequency elliptical scanning: suitable for high-voltage product type, factory test, new product development test, motor, transformer, cable, etc. Quantitative testing of partial discharge of other high voltage appliances.
Suitable for switchgear, transformer and GIS partial discharge on-line detection and location;
High-speed AD conversion circuit completes signal digitization;
Equipped with complex TEV sensor, ultra-high frequency sensor, high frequency, current transformer and high sensitivity ultrasonic sensor;
Equipped with complete functions;
GIS switch drive mechanism fault detection;
Prevent the switch from malfunction.
Principle of detection
Continuous detection of UHF, ground electric wave and ultrasonic signals to determine whether there is partial discharge
The real-time display of the measured signal change trend can make a more intuitive judgment on the development of partial discharge signal
It has the function of on-site storage of data
