With recent innovations in electrical and computer technology, portable CR (Computed Radiography) and DR (Direct Radiography) have been increasingly used throughout the industrial spectrum over the past 2 years. Portability, high quality imagery and ease of use have diversified the use of radiography for the assessment of critical parts, especially in power generation, aerospace, oil & gas etc. To date, there have been no effective NDT methods for GIS status diagnosis & monitoring. There has always been some potential risk when GIS was operating. This article provides a new, advanced NDT solution to reduce this risk and describes a number of successful application stories.
