In the context of the power grid, the potential threats posed by drones should not be underestimated. Unscrupulous individuals may manipulate drones to approach power grid facilities and use the filming equipment carried by the drones to conduct reconnaissance on the internal layout, security situation and so on, so as to gather intelligence for subsequent sabotage activities. What's more serious is that drones can carry dangerous items such as explosives and conductive materials and deliberately attack the key equipment of substations, transmission lines and the like, triggering malfunctions like short circuits and equipment damage, and consequently leading to power outages. In addition, if drones collide with transmission lines during flight, it may also cause damage to the lines and affect the normal transmission of electricity.
