Why are ultra high voltages used to carry electricity over transmission lines?
In general, it is cheaper to transport power long distances at higher voltage levels. Do not take this as a rule as always being cheaper, otherwise you would have a 500kV line into your home.The resistance in the power company's lines is not zero. There is always going to be some loss in quality whenever energy is transferred. Thus, when electricity is transferred, the power dissipated by the lines, even lines with a REALLY small resistance, like 1 micro-ohm per mile, adds up when one counts the millions of linear miles across which electricity is transmitted. The power dissipated can be calculated with the formula, P= VI, which through Ohm's law becomes P = (I^2) x R, where P = Power dissipated, V = voltage, I= current, and R= resistance. Thus, using the same resistance wire and the same power source, a higher voltage will have a lower current and less power will be dissipated as heat.It is not cheaper to transport electric power at high voltages. What we are looking for is the smallest amount of loss during that transfer. The higher the voltage the lower the percentage of loss for a given diameter of wire. The costs associated with stations to step up and down power and to maintain these stations is very high. What the goal is here though is making as much power as possible reach our final destination. This is also why we use aluminum wire for transfer rather then copper. It is all about reduced loss, cost is a secondary concern.
