The majority of devices and equipment that make life easier needs electricity to work. They are around us in our offices, shops, rooms and streets too. have you ever thought how has electricity been managed to reach us and all what we need to do is to plug the wires and perform our devices? Generation process needs an areas, huge equipment, and arrangements. That is mean the generations process stations are always in one terminal place or central while the distribution and transmission networks take the function of linking the sprawling spaces and transmitting energy through them. To control these processes, to correct and well planned device design need to be made relying on engineering and economic studies taking into consideration the amount of power needed in each area with respect to the available free areas. Therefore, the more correct is the design the extra efficient is the network. After operating the electrical network, It is always face number of factors that will affect its efficiency. improving methods to keep the efficiency is a should to save effort, money, and environment.
