Description

Line survey: infrared measurement, corona measurement, visually detectable defects using high-resolution camera and Airborn laser scan (lidar) for e.g. distance measurements on the high and extra high voltage lines. Line inspections in the high voltage and extra high voltage network through infrared thermography/daylight corona and visual inspection by helicopter incl. the technical evaluation with recommendations for action for Belgium (grid Elia) and Germany (grid 50Hertz).
