Abstract
Abstract
Lead is widely used in the installation of high voltage cable accessories. Defects in lead tend to cause serious electrical accidents. However, there is no means to detect the sealing quality yet. In this paper, laser ultrasonic synthetic aperture focusing technology (SAFT) technology is applied to the detection of lead sample defects. The SAFT algorithm is used to locate and image the various types of defects in lead samples. The results show that SAFT laser ultrasonic is suitable for detecting sub-millimeter small defects in the lead. This technology has some application prospect in the detection of high-voltage cable sealing lead layer quality.
