TRANSMISSION LINE

Transmission lines are popularly known by many especially by those with minimal background with electrical power system as steel structures with conductors attached to it and fortunately, they are somewhat right. The image below shows an overhead line with conductors which are suspended from the steel structure and are insulated from it and from other conductors by insulators. Widely used insulators for transmission line are the polymer type   and the traditional porcelain type. With the case of insulators with porcelain, the number of which is determined by the voltage of the line. 

Typical Transmission Line
Transmission lines can be designed in many ways depending on the terrain and the electrical parameter requirements. In power flow analysis, transmission lines are usually categorized in to three approaches; short, medium, and long transmission line. Distinguishing one category from one another is determine through the circuit kilometer of the transmission. 
Transmission line analysis is important since it provides us an opportunity to understand the effects of the parameters of the line on bus voltage and power flow.

When we understand more the effects of power flow to these lines, by then we can also understand more the transmission line losses that goes with it. Transmission lines, Distribution lines and Secondary lines is usually the major contributor to the power losses of the entire system.
