With there relatively inexpensive price tag and easy to operation, drones have become an indispensable tool for power liner inspection. Power lines spanning vast distances are the circulatory system of modern power grids. They present unique maintenance challenges due to their geographical dispersion, as well as their height. Traditionally inspected by walk drive takes too much of time and money and helicopter-based methods costs more and helicopters are noisy ecologically unsustainable and expensive. They can be more easily and efficiently inspected using UAVs
Drones are capable of capturing high quality images and 4K video the images these cameras captured are detailed enough for fine post-inspection analysis while the live feed will allow operators too see significant problems as they fly
Drones are being widely adopted by energy and utilities companies for a variety of applications.
Drones provide safe, efficient inspections for applications across the energy industry, including traditional power generation and transmission & distribution
Drone technology can drastically reduce inspection time, save labor costs and reduce hazardous man hours.manual inspections are time consuming and often involve climbing or using buckets, which introduce hazards that drones help avoid utility workers are susceptible to such occupational hazards as working at high heights, high-voltage contact, and working in confined areas, inclement weather or unsafe zone
Drones has effective Thermal imaging techniques and proprietary air frames to capture engineering-grade levels of accuracy for use in detailed point clouds analytic including Geo tagging to localize specific area of inspection and a proprietary back end processing solution to enable companies with instant sourcing and identification this allows to effectively inspect transmission/power lines
The ability to see a hot spot and theseverity of the problem allows the engineers to make the determination that, “this isn’t going to fail tonight, but maybe tomorrow.”
Having access to a thermal camera drone helps to prioritize and schedule repairs
The benefits of catching hot spots early include extending the life of otherwise well functioning equipment; prevention of equipment failures that could lead to widespread outages; and reduction of costs through maintenance as opposed to replacement of damaged equipment.
Thermal imaging really allows us to see what the naked eye can’t see.It allowsto fix these problems before a failure, and it has been a huge benefit to the utility.
With the corridor mapping we carry out the high resolution mapping of networks and artificial infrastructures and natural corridors which have linear development,
Through MAPPING platform installed on drones, we can perfectly map and scan the inspected line by processing detailed three dimensional point clouds from which extracting the information necessary to characterize the elements of interest. We can map wide areas very quickly.
The use of the drones guarantees great reliability and accuracy in the mapping, since it allows us to carry out the survey keeping the sensors at close range from the object of the mapping, that can be thus inspected in a very detailed way.
Starting from the images captured by the digital cameras during the flight, the products we create according to the client's needs are different: from DTM, DSM and orthophoto
Transmission line inspections for vegetation management and other purposes are essential in ensuring grid reliability and resilience.
These inspections are generally performed by manned helicopters or by a ground crew. Data is collected with cameras and analyzed to detect diseased trees that could fall and hit a power-line or trees that are encroaching on power-lines .But both types of inspection approaches have limitations: they are expensive and time-consuming, introduce safety risks, are not always complete, accurate or timely, and in some cases, given terrain and air space restrictions, are not even practical.
Beyond visual line of sight drones and software analytics using machine learning have become a viable approach in many areas of the world.
With drones that can cover great distances in a single flight and provide detailed and accurate aerial imagery of transmission lines and other infrastructure, it is now possible to almost completely automate this expensive process. Automating transmission line inspections for vegetation management usingdrones not only saves money, but also could improve the resiliency and reliability of the transmission grid.
The power transmission lines are the link between power plants and the points of consumption, through substations. Most importantly, the assessment of damaged aerial power lines and rusted conductors is of extreme importance for public safety; hence, power lines and associated components must be periodically inspected to ensure a continuous supply and to identify any fault and defect. To achieve these objectives, recently, Unmanned Aerial Vehicles (UAVs) have been widely used; in fact, they provide a safe way to bring sensors close to the power transmission lines and their associated components without halting the equipment during the inspection, and reducing operational cost and risk. In this work, a drone, equipped with multi-modal sensors, captures images in the visible and infrared domain and transmits them to the ground station. We used state-of-the-art computer vision methods to highlight expected faults (i.e., hot spots) or damaged components of the electrical infrastructure (i.e., damaged insulators). Infrared imaging, which is invariant to large scale and illumination changes in the real operating environment, supported the identification of faults in power transmission lines; while a neural network is adapted and trained to detect and classify insulators from an optical video stream.
