Comparison of the Application of 3G and COFDM in UHV Transmission Lines Inspection

With the rapid construction of UHV power grid in China, the difficulty of transmission lines inspection and maintenance has increased dramatically. Thus it is urgent to adopt new technologies to replace the traditional manual mode of transmission lines inspection and maintenance. In this paper, the characteristics and applications in UHV transmission lines inspection of 3G and COFDM technology are analyzed and compared.
