I’m guessing one of these big boys came down In this area. WWL-TV(CBS) has confirmed it was a transmission tower that went down and damage to the remaining transmission lines that feed Orleans Parish. WWL was also knocked off the air briefly.

drstuess Posted August 30, 2021 Share Posted August 30, 2021 How states, counties, townships etc along the coast, allow surface transmission lines is beyond me. Makes absolutely no sense. Let’s put a tree in the ground and attach 480 to it. Hopefully since we call it a pole it will survive 150 mph winds… insanity480? Distribution is usually 12.47, 25, etc kV, so MV; 480 is LV. Transmisison usually much higher, > 100 kV. Either way, reality, is underground and ring/euro RMU style distribution is much more reliable, but brownfield is 7 figures per mile. Either way, if your transmission towers fall into the Mississippi not much you can do. Microgrids could get power to back to some sooner, but tough and general favor the ones with the means.Sent from my SM-G960U using Tapatalk 3 Link to comment Share on other sites More sharing options...

The tower that fell into the Mississippi can have the line be temporarily rerouted in a matter of days if the area isn't under water. Europe has overhead transmission lines in rural areas and over long distances. They don't have overhead local distribution in denser areas. America does, and america is less dense, but more of that has to do with the us allowing rampant, ugly sprawl to occur anywhere, and it's invention of the disaster that is the modern car dependent suburb. If everywhere else that is developed can afford to bury power, so can the usa, but if it's a major transmission line here, that's not the issue. The larger issue is needing the line in the first place to service thousands living in an area that will constantly, and increasingly meet with disaster. 5 2 Link to comment Share on other sites More sharing options...
