Using drones to inspect overhead power lines is safe as long as the pilot operating the drone is fully qualified.  The drone cameras and sensors are so advanced now that you do not need to get close to the lines or tower and still get detailed images.

High quality RGB camera, thermal sensor and UV are required to get the best results.

This would depend on the pilot’s experience and the number of drones that are used at one time.  With the right drones and pilots, you can fully inspect around 50 towers per day.

We would recommend the EVO Max 4T for this type of inspection.  One of the reasons for this is that you can fly more than one drone at the same time safely.

The frequency of drone inspections depends on various factors like the age of the infrastructure, environmental conditions, and regulatory requirements. Generally, power companies conduct regular inspections, which can be up to several times a year.

Drone inspections for power lines are highly accurate and reliable, especially when using high-quality equipment and experienced operators. They provide detailed visual and thermal data, which can be more comprehensive than manual inspections.
