New drone from SDU is ready to inspect powerlines

Denmark has above 7,000 kilometers of high-voltage cables. To make sure electricity in the sockets, the cables should be inspected frequently for faults and corrosion.

Right now, the inspection process is carried out by staff members in raise trucks or helicopters, but that is expensive and entails dangers due to the top.

Now, scientists from the Maersk Mc-Kinney Moller Institute at the College of Southern Denmark have designed an intelligent drone to have out the inspection.

Swarms all-around the cables

The drones are to fly in swarms all-around the cables and constantly check out for faults. If the drones find anything to be fixed, a information is despatched house to the operator of the cable. The drone quickly recharges its battery in the magnetic area all-around the overhead line, which indicates that the inspection can mostly be remaining to the drones by themselves.

– In this way, we only require to send staff members up in the air when there is a real require for repair service. This will make it significantly less expensive to preserve the strains, claims Lars Rasmussen, high-voltage engineer and group leader at Energinet.

– The best aspiration, of program, would be to obtain the similar setup as with a robotic lawnmower at house, this means a answer where by the drones fly autonomously, check out for errors, cost, and send experiences house. We are really fascinated in implementing this, he states.

The Grand Alternative Innovation Fund Denmark undertaking, which is known as Drones4Energy, originated from the Danish government’s national drone technique from 2016, where by inspection duties had been highlighted as an spot with great possible.

Soon after numerous several years of growth at the college as very well as SDU’s tests facilities in HCA Airport in North Funen, the scientists are now ready to test the intelligent drone system in collaboration with Cerius, Energinet, and other fascinated companions.

– The new drone will function in a swarm system, where by numerous of the new drones collaborate to examine the electricity grid, explains Emad Samuel Malki Ebeid, affiliate professor, and undertaking manager of Drones4Energy.

– The drone detects the high voltage cable applying onboard sensors. It has developed-in cameras that get pics and an algorithm that acknowledges and identifies the errors that the pics may possibly demonstrate.

– For the system to purpose constantly, it should recharge alone. We have designed a answer for this, where by the drone recharges from the magnetic area all-around the high-voltage line. That will help you save time and prices, he claims.

Invitations new companions

The intelligent drones will be operating in a severe atmosphere. There are 230 volts in the sockets in our homes, but the voltage on the overhead line is 400,000 volts. That is plenty of for sparks to strike, and it generates some troubles for the sensitive sensors the drones are geared up with.

The crew of researchers has hence designed a unique shield that guards the drone system, even when traveling really close to the cables.

– Now all the aspects should be set alongside one another and integrated, and we would really a great deal like to enter a dialogue with general public and private actors who see a possible in the know-how, Emad Samuel Malki Ebeid claims.
