Product Introduction
MOEORW-WAA 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.

FAQ
Q1: Can it detect partial discharge through sound insulation materials?
A: No. It detects ultrasonic signals propagating through the air, so there should be no obstacles between the sensor and the detected part.
Q2: What is the detection angle of the ultrasonic probe?
A: The beam angle is 50°±10° (-6dB), and the universal bracket allows 360° adjustment to cover all detection directions.
Q3: Is it affected by ambient noise?
A: The 40KHz center frequency is far away from the audible noise range, and the metal shielded housing effectively suppresses electromagnetic interference.
Q4: Can it be used for both handheld inspection and fixed installation?
A: Yes. It can be used with a handheld detector for inspection or fixed with a universal bracket for long-term online monitoring.
