What is the difference between overhead transmission line and under ground transmission line?
Um. One is hung above your head on telephone poles and the other is ran underground in conduit? Unless you meant something else?
Also burying cable costs ~10 times as much for transmission lines as overhead. It also usually has a lower power carrying capability, since it cannot dissipate heat as readily as an overhead conductor.
What else can I help you with?
What is underground power transmission?
power cables under ground rather then overhead.
Why delta connections used in overhead transmission lines?
There are essentially 2 types of connections for a 3 phase AC transmission lines Star and Delta , Star is a 4 wire connection with each phase supplying potential with respect to a common ground wire , while delta is 3 wire connection with any single phase at one given time acting as a ground , for transmission reducing one wire makes a lot of cost difference hence it is favored
What is the difference between first floor from ground floor?
Actually, there is not much difference, but a ground floor is usually the very bottom one and the first floor is usually the one above
What is the difference between granite crusher and crusher skylanders?
The Granite Crusher has an upgrade of a Ground Grinder where the Crusher does not.
What is the difference between well and tubewell?
The difference between a well and tubewell are the amounts of water they supply. Wells can supply any amount to certain locations like crops. Tubewells involve pumping ground water in specifically measured amounts.
What is the purpose of ground wires in overhead transmission lines?
connection of the ground of all the transmission lines and used as a communication cable between protection devices
What is underground power transmission?
power cables under ground rather then overhead.
What happens to the ground when there is a thundercloud overhead?
When a thundercloud is overhead, the intense electric fields generated can induce a positive charge on the ground below. This in turn can result in the ground becoming positively charged, leading to a potential difference between the cloud and the ground. If the potential difference becomes large enough, it can result in a lightning discharge.
Difference between overhead cables and under ground cables?
The principle difference between underground and overhead cable is thermal dissipation. With overhead cable, heat can dissipate into the air, and wind can improve the rate of thermal dissipation. On the other hand, overhead cable is exposed to solar gain that will result in some heating. With underground cable, heat dissipation is governed by the thermal conductivity of the soil. The Neher-McGrath formulas can be used to calculate thermal conductivity and the required derating of conductors. Comparing the two, an overhead cable generally has a higher thermal ampacity than an underground cable of the same material, dimensions and insulation.
What is difference between original ground level and normal ground level?

What is the difference between ground espresso and ground coffee?
The main difference between ground espresso and ground coffee is the fineness of the grind. Ground espresso is much finer than regular ground coffee, which results in a stronger and more concentrated flavor when brewed.
Why delta connections used in overhead transmission lines?
There are essentially 2 types of connections for a 3 phase AC transmission lines Star and Delta , Star is a 4 wire connection with each phase supplying potential with respect to a common ground wire , while delta is 3 wire connection with any single phase at one given time acting as a ground , for transmission reducing one wire makes a lot of cost difference hence it is favored
What is the difference between Stolon and Rhizoid?
rhizoids are below-ground, stolons are above-ground
What is the difference between airspeed and ground speed?

What is the difference between underground and above ground?
underground has soil or is wet and above ground is dry or grassy

What is the difference between tube and rail?
tube is underground but rail is on the ground :)
