Key Technology of Nondestructive Testing of Solid Insulating Materials in Power Equipment

Abstract

Power system is the center of modern society, but there are always various faults in the process of power system operation. Detection technology is very important for the good operation of power system. Nondestructive testing technology, as a special part of detection technology, has broad development prospects. This paper mainly focuses on the four common nondestructive testing methods of X-ray, ultrasound, CT and partial discharge in nondestructive testing technology, analyzes and prospects the current research status from different angles such as the characteristics, innovation and detection system of testing methods, summarizes the current research progress, and looks forward to the frontier problems in the future.
