An overhead power line is a structure used in electric power transmission and distribution to transmit electrical energy across large distances. It consists of one or more uninsulated electrical cables (commonly multiples of three for three-phase power) suspended by towers or poles.
Since most of the insulation is provided by the surrounding air, overhead power lines are generally the least costly method of power transmission for large quantities of electric energy.

Economic Benefits

A blackout in a single area can cost approximately $1 billion, and major regional blackouts can cost $10 billion.

Security Benefits

A modern grid can contribute to energy security by reducing the energy system’s vulnerability to terrorist attacks and natural disasters.

Environmental Benefits

Modernizing the power delivery system is an essential step in reducing emissions of carbon dioxide and other pollutants such as SOx, NOx, and mercury.

High voltage power lines are used for the transmission of electricity over long distances.
Electrical transmission is the process of delivering generated electricity - usually over long distances - to the distribution grid located in populated areas. An important part of this process includes transformers which are used to increase voltage levels to make long distance transmission feasible.
The electrical transmission system combined with power plants, distribution systems, and sub-stations to form what is known as the electrical grid.

The grid meets society's electricity needs, and is what gets the electrical power from its generation to its end use. Since power plants are most often located outside of densely populated areas, the transmission system must be fairly large.

What is a safe distance to live from high voltage power lines?
The strongest magnetic fields are usually emitted from high voltage transmission lines — the power lines on the big, tall metal towers. To be sure that you are reducing the exposure levels to 0.5 milligauss (mG) or less, a safety distance of 700 feet may be needed.
Overhead Lines are very high voltage, between 100 kV and 800 kV, and do the majority of long distance transmission. They must be high voltage in order to minimize power losses to resistance.
Underground lines are used to transport power through populated areas, underwater, or pretty much anywhere that overhead lines can't be used. They are less common than overhead lines due to heat-related losses and higher cost.
Subtransmission Lines carry lower voltages (26 kV - 69 kV) to distribution stations, and can be overhead or underground.
