The CR and DR Detection Contrast of Power Cable Defects Based on X-ray Digital Radiography

This paper summarized the digital imaging system composition and working principle of CR and DR. By using three artificial defects under laboratory conditions, the detected results by CR and DR were compared under two different X-ray sources. The experimental results show that both CR and DR can effectively detect power cable defects and present finding is hoped to provide reference basis for the defect detection of power cable.
