Helicopter surveys high-voltage grid in northern Netherlands
TenneT inspected six high-voltage connections in Drenthe, Groningen and Overijssel this week. During the flight, the helicopter took aerial photos and scans of high-voltage connections using special cameras and sensors. It is the first time we used a helicopter for this. Siemens Energy carried out the work for us.
40 to 50 metres high
To properly map the high-voltage connections, the helicopter flew along both sides of the high-voltage connection. The helicopter flew at a speed of 25 kilometres per hour and at a height of 40 to 50 metres.
Thanks to the rich and detailed data, we gain better insight into the above-ground part of the electricity grid and can organise management and maintenance more efficiently. And keep high-voltage connections in optimal and safe condition. If the approach proves successful, we also want to map the rest of the high-voltage connections in the Netherlands in this way.
Benefits of helicopter flights
Gathering information about the high-voltage grid and the immediate surroundings is now often done manually. These measurements are time-consuming and costly. With our new approach, we need to take fewer measurements and can deploy technical colleagues on other projects.
The data generated by the helicopter flight is uniform and enters a special management environment. This allows us to advise local residents and landowners in the vicinity of high-voltage connections more quickly about the possibilities for activities and construction.
Besides the connections, the immediate surroundings of the connections are also analysed. Based on the data, we can for example create an effective management plan for vegetation.
