Georeferential Video for Located Access Road and Stringing Tension Equipment Places to Install 1366 km OPGW Cables in Existing Transmission Lines

One of the most important activities of predictive maintenance of the transmission lines is the periodical inspection of each component (insulators, conductors, structures and others), besides the bio-physical environmental between them. This activity requires high efforts of the technical resources and also an important amount of money. CVG EDELCA, the big utility company in Venezuela, has been operating 2100 km of transmission lines in 765 kV, more than 3200 km in 400 kV, also 500 km in 230 kV and 115 kV. All of them have corridors that involve a very extensive areas that must be monitoring and the information obtain about the monitoring activity must be actual and available in real time and adequate formats for the good management decisions. Understanding the advantage of the new technologies in the multimedia area, CVG EDELCA since 2000 has been working with this technology in the transmission lines engineering designs (route study, survey, etc). Recently CVG EDELCA has been using this technology for preview ground wire replace studies for new optical ground wire (OPGW) in transmission line in operations, this experience is describe in this report
