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 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.
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.

What is the difference between Stolon and Rhizoid?
rhizoids are below-ground, stolons are above-ground
Difference between overhead cables and under ground cables?
Overhead cables are installed above the ground on poles or towers and are generally easier to access for maintenance but more exposed to weather conditions, while underground cables are buried beneath the ground, offering better protection from environmental factors but requiring more complex and costly installation and repair processes. Vazpo sells a wide range of cables including overhead and underground cables.(www. vazpocable. com)
