The other grids are the distribution grid for the supply of industrial companies and the distribution of electricity on the way to the end consumer, the local grids for the supply of larger customers such as hospitals and for further distribution and finally the low voltage grid for distribution and supply to end consumers such as small companies or private households. The largest traverse is at the bottom, the second largest in the middle and the smallest at the top, resulting in the typical fir tree shape. the fir tree mast was compared to the barrel mast.the delta mast, in which the conductor traverse sits on a V-shaped fork,.the portal mast, which consists of at least two supports that promise great stability but require more space,.The middle cross beam is the widest, resulting in the typical barrel shape, the barrel mast, which consists of three superimposed traverses.the Danube mast, which consists of two superimposed trusses, with the narrower one usually at the top,.The usual voltages are 220 kilovolts (kV) or 380 kV. In Germany, the companies Tennet, 50 Hertz, Amprion and TransnetBW take on this task as well as the maintenance and expansion of the transmission grid. The transmission grid is responsible for the long-distance transport of electricity. The power grid in Germany is divided into four levels, some of which have specific pylons. But before we get to the advantages of the drone inspection, let’s briefly sketch the power grid and some different mast shapes. Today there are more than 350,000 pylons that have to be inspected regularly. The first electricity pylons were erected in Germany as early as 1892. Regular inspection is essential for a reliable power supplyġ) The drone is unbeatable in terms of occupational health and safetyĢ) Finally collecting reasonable stock dataĮasy integration of drones through good project management Over 125 years of history meet drones The efficient FlyNex project management solution ensures scalability, especially for drone projects. The inspection of power pylons is a labor-intensive and cost-intensive activity that can be carried out more safely and efficiently with the help of drones. In Germany, they reach heights of up to 227 m. I can tell you with a high degree of confidence that getting within a quarter of mile of a cell tower is not going to cause any harm or erratic behavior in your Phantom.Particularly in rural areas, overhead line pylons, as power pylons are actually correctly called, are a formative image alongside wind turbines. They may require the the tower owner to turn everything off before they will get near it. There are several companies that use UAV's for tower inspection and I will be honest, I don't know if they will inspect a tower with the equipment hot or not. My concern is that the energy from the dish would overload 'fry' the receiver on the Phantom's radio. One thing I am very careful of is not to fly near the microwave dishes, especially directly in front of or behind them, that's where the energy from them is strongest.

I've flown near our towers (on my own and just for fun, not for work! I had to include that disclaimer in case the FAA is reading) and have been within 20 or 30 feet and have never had an issue. Our microwave links are all unlicensed and operate in the 2.4 GHz band the same general area as our Phantoms. We also have some equipment that uses the same types of radios as cell phone towers, so they operate in the same frequency bands 900 MHz. Part of my job for my company is to maintain our microwave radio network for our two way radio towers. Great info and discussion, thanks for the comments, very useful. If you aren't up for a confrontation, read that list Posted at 01:46 Yes, many aren't technically illegal and you aren't likely to get caught, but unless you are intentionally poking Big Brother in order to get footage of them overstepping their authority, you are just asking for trouble and possible confiscation. Call it Fascism, but is it something you want to test?Īirports and any place where aviation is active (such as a hospital with helo pad or an active wild fire)Īnd.shooting ranges (you're just asking for it.) and anyone doing anything questionable around them is just asking for a visit from the police or feds and possible confiscation of copter, possible prosecution, possibly being placed on lists you don't want to be placed on. Now, would I test that theory? Heck no.ġ) If something goes wrong, whether it is or is not the fault of the power lines, I would hate to have to explain why my 'toy' was tangled in those lines.Ģ) Power transmission lines (big, interstate types) are considered critical infrastructure in the U.S. and in my opinion they wouldn't be a likely threat.
