Applications

Product Overview

    MOEORW-AA is a partial discharge detection sensor based on the airborne ultrasonic principle, specially used for detecting surface discharge phenomena of insulators, bushings, busbars and cable terminations. When partial discharge occurs on the insulation surface, it generates mechanical vibrations that propagate through the air medium, which are captured by the high-sensitivity ultrasonic probe of this sensor.

     The sensor adopts a universal bracket design, allowing 360° adjustment of the detection angle for accurate inspection of all parts of the equipment. The specially treated metal housing provides excellent electromagnetic shielding performance, enabling stable operation in strong electromagnetic interference environments. With IP68 protection, it can be used in harsh weather conditions such as rain and fog.

Application
  • Insulator and bushing surface discharge detection
