Augmented reality system for maintenance of high-voltage systems

Augmented Reality (AR) promises to revolution the maintenance field in general with relevant contributions to High-Voltage Systems. The value-added can came from several aspects, namely the increasing security and reducing time and costs of intervention. However there are some aspects related to AR state-of-the-art that do not permit yet to reach all of their potential, namely the necessity of use of markers in many situations and the necessity of 3D modeling for markeless situations. These are the main aspects presented in this paper as well as the nowadays main trends. Several experiments are also detailed and referenced to attest the benefits and actual restrictions and gaps of Augmented Reality applied on industrial scenarios. Close to teleoperations, it is demonstrated how solutions that combine virtual and real scenes may improve technicians' performance and reduce the risk of fatal accidents by improving training conditions.
