3252: Potential Applications of Spatial/Object Recognition Technologies for Transmission Lines

The identification and assessment of available technologies for the automated image-based recognition of components and hardware installed on electrical power transmission lines was conducted. The need for this capability stems from the numerous components and their variations installed over a long service period and the lack of databases containing component identities and locations. The desired recognition system would enable transmission system operators to develop/maintain a database of inst

3220: Use of Non-contact Laser-Ultrasonic Method to Detect Cracks in the Shell of Porcelain Insulators Phase I: Feasibility Study - Laboratory Testing and Development

The objective of this project was to use non-contact laser-ultrasonics to excite acoustic vibrations in insulators using a generation laser and to measure the vibrations using an optical interferometer. Various inspection techniques were tested on a number of cracked and uncracked porcelain insulators. Only samples with large (a few centimeters long), visible cracks in the insulator shell were available for testing. The non-contact laser-ultrasonic inspection method tested, employing pulse laser

3242: State of the Art Study on Unmanned Aerial Vehicles (UAVs) for Transmission Line Asset Management

Electric power utilities employ a number of inspection techniques to identify safety, maintenance and reliability issues and acquire the information that is needed to manage transmission line assets. In many cases, routine inspections and asset condition assessments are carried out using helicopters with trained personnel to capture information for an intended purpose. As another tool to help meet customer requirements for availability and reliability, the application of robots to automate the i
