X-ray digital imaging detection system for high-voltage equipment inspection

Abstract

In 2019 a portable diagnostic X-ray system was developed and tested for the inspection of high-voltage equipment (HVE). The system operates based on discrete radiography and is referred by the authors as the first generation X-ray system. As a result of critical analysis of the first generation system, it was further proposed to create a second generation mobile scanning system for HVE digital radiography which is for the first time applied in the power engineering. A physical and mathematical model was developed to establish the relationship between the energy spectrum of the source X-ray radiation and the contribution of this radiation to the image generation during HVE radiography. Using this model, the authors assess the efficiency of the unique X-ray machine used in the first generation X-ray system. The main technical requirements for the second generation X-ray system, implementing digital scanning radiography, for examining HVE in operation are given.
