Final answer:
Most transmission lines can be inspected quickly using UAVs, helicopters, and infrared imaging for real-time data on the power lines' condition after an outage. Advance warning of solar storms allows power networks to run at lower capacity to absorb surges. Tension in the lines, affecting oscillation, is maintained by how they are stretched and anchored.
Step-by-step explanation:
To inspect transmission lines quickly after they experience a sustained unscheduled outage, various methods can be used.
One efficient approach is the deployment of unmanned aerial vehicles (UAVs), commonly known as drones, equipped with cameras and sensors.
UAVs can cover large distances swiftly and provide real-time data on the condition of the transmission lines.
Additionally, helicopters may also be used for rapid aerial inspections.
The use of infrared imaging to detect hotspots indicative of electrical failures is another method. For lines that are difficult to access, satellite imagery might be employed, although it is less detailed than UAV or helicopter-based inspections.
Maintaining the resilience of power networks is crucial, especially during solar storms which may cause power surges.
To minimize the disruptive effects, advance warning systems are in place to allow power networks to operate at reduced capacity, enabling them to better absorb any spikes in power.
Lastly, the tension in power lines, which affects the speed of the waves on the lines during wind-induced oscillation, is maintained by the mechanical force originating from how the lines are tightly stretched and anchored between structures.
