Mr. Carreira received his B.Sc. in Electrical Engineering from the University of Waterloo and held engineering and management positions at a major electric utility before becoming President of K-Line Insulators. He serves on committees in CIGRE, IEC, CSA and IEEE and, with 40 years industry experience, has authored and presented technical papers on topics ranging from latent transmission power line hardware damage to insulator technology to the state-of-the-art of live line work. He received the 2014 Claude de Tourreil Memorial Award for Lifetime Achievement in the Field of Electrical Insulators and has been recognized as presenter of the Most Innovative Paper on New Live Line Tools and Framing Arrangements at ICOLIM. He is also recipient of an Honorary D.Phil. from the Budapest University of Technology & Economics.
Traditional live line systems and tools are constructed using fiberglass-reinforced plastics coated with epoxy. However, these devices can ‘wet out’ and are for fair weather conditions only. Such tools also cannot normally be left on energized equipment for long periods or used during rain or other humid conditions. This presentation offers a new approach to design of live line tools based on materials typically used in polymer insulators and also includes application of robotic devices. It will explain how designing a new generation of tools allows greater flexibility in how long they can remain installed or be left in service should the weather change.
