It is important to state that the proper transmission of electric energy must be effected through a system of devices, such as transformers and electric conductors, called transmission lines, which transmit the electric energy produced in the generating units to the consumer units or loads. The transmission system makes it possible for the electrical voltage coming from the terminals of the generators found in the generation units to reach the power supply of the consumption units required by the system.
The system whose function is to perform the transportation of electric power from the generating units to the consumer units is basically formed by three subsystems. The power generation system is composed of elements and components responsible for the process of converting energy from any primary source into electrical energy and into other components of the generation units.
In this way, it is worth mentioning that the transmission system consists of components responsible for the process of transporting the energy obtained through the different generation systems to the distribution systems that are interconnected by the transmission system. The distribution system is composed of the elements that must act in the adequacy of energy for the use of large, medium and small consumers.
