## 5 Opportunities and Alternatives
### Electrical Sector Applications  
In the installations of electricity companies, it is becoming more common to employ different methods to perform regular jobs that were previously performed manually. The structural aspects of the power lines should be monitored to keep the power distribution running in countries. Therefore, the use of UASs helps such companies as the Korea Electric Power Corporation (KEPCO) perform diagnostics on their distribution and power lines through a drone project [93]. Similarly, other electric utility companies have begun to \begin{table}

Another application in the electrical industry is carried out: the use of deep learning to build a real-time power line detection network, based on convolutional neural networks from images of visible light and infrared images taken by several UAVs, to avoid other self-driving drones colliding with electrical power facilities [94]. Similarly, the British Columbia Transmission Corporation (BCTC) has considered including UAVs in routine and emergency line inspections to prevent injuries to their employees and reduce costs and greenhouse gas emissions. BCTC has around 18,000 km of high-voltage transmission lines through the mountains of British Columbia and uses helicopters with crew inspectors; this type of work is considered dangerous and expensive, and the advantages of using UAVs have been seen to replace them [95]. At the same time, visual inspection has become an advantage to apply in rural electrical installations [96]. Electrical discharges caused by the corona effect are identified with digital image processing applications. In a fog environment, insulators are prone to discharges; therefore, observation and analysis of the phenomenon can help improve the maintenance of the infrastructure [97]. In addition, image correction technology is shown using data analysis [98] to establish the corresponding relationship between an original image and a distorted image. This is applied to the inspection of electrical assets to obtain the best-quality images. Several studies have been developed to assess the integrity of the transformer core and windings, using frequency response analysis and visual analysis to assess the integrity of the transformer core and windings. Together, these techniques are capable of detecting various deformations of the windings [99].
