Drone Power Utility Pole Line Inspections

- It is not just safety and financial benefits driving the use of drones for Utility Line inspections.
You can expect huge time savings and better data collection. With the flexibility of numerous camera payload options , drones are simply more efficient. Drones easily complete the repeatable project in fraction of the time it takes trained inspectors.
There are several different components making up a power grid. There are stations, different load level lines and tower types. These all require different techniques of inspection. In this video, we discuss the benefits of using drones for Utility Power Line Inspections and some details of the process.
Libitron Aerial Drone Services is here to help you operate your business in the most efficient ways possible. We can offer inspection services and help you develop a program. Please contact us to discuss how we may serve your needs.

In the video what exactly were you looking for from a thermal perspective? Majority of the poles in the video had no connections on them so I assume those poles were a visual inspection only. What is the temperature limit you use that you would determine a hotspot? Thanks
I`m in a home inspection (facade) small business. Really liked the digital twin for reporting issues and reports for customers. I don`t have the necessity for asset managing. Whatou would be the ideal drone/software to work under this scenario? Most of soft. aims asset management and have prohibitive prices for small business inspection. Great Video!
Ideal drone ..... seems like an easy question but it is not really. If I understand you well enough, you are looking for a thermal solution for inspections including facade. For most of the inspections you will be fine with a relative measurement because you will either be trying to identify insulation issues or water issues. The insulation issues are a bit tricky without a radiometric camera however even though relative temps show you where there is a change in temp. I find myself using the radiometric thermal for those inspections because the thermal output display just appears to be a dramatic difference when in most cases that is not correct. So I would say at minimum you have to have a thermal setup that can provide at least a temperature legend so you can identify what each display colour represents. So I think a good drone for you is one that can provide at the very least that information. It is very easy to just name a drone but I think you should do your homework and decide what model suits you. I am just offering my opinion on minimum specs. The truth is that adding a Vue model to a drone is a great option even though it will likely end up in a fixed position. I see those coming up for sale all the time in the Flir Facebook groups. The thermal decision may be more important that the RGB since most drones will work for the inspection. What you do have to do is make sure that the drone is compatible with the mission planning software that you choose. I think drone harmony is a very good platform for facade inspections but this is another thing that is very fluid and changes so fast. The is all a very long answer to finally say that you have to do your homework. I hope my intention is clear in my answer and I wish you all the best.
Could be a little bit more interesting, if you would show, how really grid problems looks like, and not only good grid state. Because so, people could not really understand, for what you need such method of inspection.
This inspection strategy is a matter of maintenance. The purpose is to spot developing problems.

In this video the speaker speaks about much advantages by inspections and searching of grid problems, by using of such methods, like drone with visual and thermal camera. But video doesnt show this advantages, how this looks like. We see only new grid in good shape, without some problems, without demonstration of advantages and so on. I expected to see, for example damaged insulator, where in visual camera is nothing to detect, but in thermal camera this insulator is shining like lamp from warmth. To see bad distributed power on lines, which have different temperatures, too small dimensioned or damaged transformer, which is very hot, and so on.
4:54 has a damaged field side terminator, probably no thermal signature yet but an experienced eye could report it, create a work order, or being so new have the contractor who built it make warranty repairs before its a real problem.@@konstantinhuwa3064
Which UAV and payload was used during this video ?
Our work Horse for this type of inspection is the M210 RTK with an X5S and 45mm lens and a Zenmuse XTR Thermal. We also use a Z30 very commonly, but since our usual procedure is to have simultaneous RGB and Thermal, the X5S is usually mounted. Some people will argue that the XT2 may be a better camera. It would offer some benefit but over all we like the XTR mainly because it is the best mapping Thermal camera we have used to date. We map a lot of commercial buildings. The sensor in the XTR is fantastic. And we also use the same RGB and thermal video for the roof inspection process. It works even more effectively with the roof inspections.
Having said all of that, if our inspection type was a little different or if we were mapping the lines, then we would almost certainly be using an M300 with A LiDar set up. Mapping lines with RGB is very difficult to get the lines to produce well in the models. RGB is fine for an ortho, but not for a model in our experience. Maybe someone else is able to pull it off, but we have not in a satisfactory way. The M30 is also an excellent choice and something we are considering to try out.
Why are these inspections necessary? And if company doesn’t do it is it wrong on there part? They it’s to expensive to change rotten poles and just fit as they fall
Preventative.
These inspections can catch what roll-by line patrols can't: loose tiewires, broken strands on linewire, broken insulators, failing equipment, or loose hardware. Even vegetation requiring trimming.
