An overview,
Ultrasonic inspection device is a detection device that diagnoses potential faults of power lines by collecting abnormal ultrasonic signals of power lines and analyzing them with software. This device is in the state of no power outage to determine the location of hidden trouble and fault type. Device by ultrasonic detector (ultrasonic sensor) after collecting abnormal ultrasonic signal, transmission to the host, at the same time, through the analysis of the host built-in software accurately diagnose the fault hazard type and severity level, and converted into audible sound signal and the output waveform, accurate inspection personnel found line fault hidden trouble, prevent the happening of the malignant fault, to avoid the unnecessary power outages, It improves the reliability of power supply, improves the working efficiency of inspection personnel and reduces the labor intensity of inspection personnel.
