The main reason why undergrounding hasn’t been fully adopted in the U.S. is the overwhelmingly high cost of installing underground power lines. Estimates place the cost of undergrounding power lines at roughly $ per foot, compared with $70 per foot to install power lines the way we do today. At over ten times the. Aug 25, · Why? In Germany, the risk of outages or power-line dangers is greatly reduced, because the power lines are underground, according to an article on Outside the Beltway, “Why can’t we just bury all the power lines?” Should cost trump all other factors, including safety and lives, when deciding whether to bury power lines in the U.S.?
I don't really want to say what I do but I get a fair bit of exposure to this discussion. In some of the nicer residential areas of town it's all underground (URD), but even getting power can be difficult- you have to run conduit to a handhole, avoid anything already buried, and get your wires tapped to the power . The potential across the battery is the voltage which you will see labeled. A 9V battery can just as easily be used as a ±V battery if the positive(+) lead was connected to a +V rail and the negative(-) lead was connected to a V lead. I've actually seen this done for an audio amp circuit, though I can't . It's possible, during your "charging moment" (you act like a capacitor), if the voltage is high enough or if you act as an antenna between a high-power transmitter and the air but it really takes some doing to get electrocuted if you are not. The choice between overhead and underground system depends upon a number of widely differing factors: (i) Public safety: The underground system is more safe than overhead system because all distribution wiring is placed underground and there are. \$\begingroup\$ The capacitance between the power leads in an underground duct is much higher than for overhead wires because the wires are very much closer together. The cable size is chosen for its current carrying capacity - so, if you demand that the power wires carry reactive current, you need to buy heavier gauge power wires. Even though lightning has been understood by science for quite some time, it's hard not to feel a bit of primal fear when watching those bright bolts split the sky. Lightning, of course, is actually a quick burst of electricity. Electricity (whether it comes from lightning or any other source) heads to the ground.
