  15. 15. The operator takes a series of high- resolution images of the tower and its elements in order to obtain the complete mosaicking of the structure. During the flight the HD video will be recorded to document all the flight operations Data Collection Use of Day Light Camera
  16. 16. Images at 36 Mpixel resolution are taken from the front… …and back side
  17. 17. Due to a very steady turret system, long focal length of the camera and all Hi- Resolution images obtained, back office technicians can see every important detail needed for an adequate post processing
  18. 18. During post processing, the images collected during the flight will be reviewed by a specialist who will search for and classify anomalies on:  Hardware  Clamps  Insulators  Components of the Towers  Foundations of the Towers  Dampers  ETC…
  19. 19. During the flight we record an entire video of the Corona inspection. When a HOT SPOT is present, the operator will scrutinize the area and will adjust the camera to obtain sharper images In the sample image, the Corona Discharge appears as a floating blob of light Data Collection Use of Corona Camera
  20. 20. During the flight we record an entire video of the infrared inspection. When a HOT SPOT is present, the operator will scrutinize the area and will adjust the camera to obtain sharper images It is necessary to take HIGH RESOLUTION mages at the same time of making a VIDEO RECORDING in order to perform a throughout analysis of all areas where a Corona Discharge is present To avoid any reflections from the aircraft, the a 45 degree tilt positioning may be necessary for this operation Automatically triggered audio sensor turns on the audio system for 45 seconds to record time and geo referenced comments from the cabin Data Collection Use of Thermal IR Camera
