The Kelvin’s law is an important equation for people in the business of buying and installing transmission lines. The mathematical statement revolves around finding what size conductor will have equal annual losses to costs, which goes a long way towards making decisions about future investments without taking into account other factors such as environmental impact or cost-of-living difference between communities that would be connected by new line installation.
The Kelvin’s Law states that when there are no externalities taken into consideration whether they be social, economic, political etc., then it becomes very easy to determine how much money should go on capital investment before having any more loss than can even begin rebuilding itself at all levels with profits coming back year after year.
The Kelvin’s law states that the most economical size of a conductor is determined by how much energy it loses every year. The more loss, the bigger and heavier you have to make your conductive layer in order to keep losing less than what you produce annually.
Why is it necessary to determine the most economic size of a conductor?
The size of a conductor is important for determining the best cost to maintain it. This can be found out by Kelvin’s law which determines that an x-section has minimum total annual costs when its area equals the economic size.
