What is a Long Transmission Line?

Long transmission lines are transmission lines with lengths greater than 150 km and voltages above 100V. It plays an important role in the transmission of energy and power over long distances supporting the functioning of modern electrical technologies. They are very long and stretched across so many regions.

To understand long transmission lines properly we need to understand the basics of some topics like voltage regulation, power stability, transfer capability, etc. If we want to learn more about the features of the long transmission line we could learn from areas like- power flow analysis, Characteristic impedance, and transmission line impedance. Long transmission lines are used in a wide range of applications which are including our day-to-day lifestyle and also for bigger purposes like industries, machinery, etc.

Some important points are

• They typically operate at high voltage levels to minimize transmission losses and transport the power for long distances.
• Voltage regulation is very important for maintaining the stability of long transmission lines.
• Long transmission lines line has resistive losses due to corona losses and skin effect.
• Long transmission lines require regular inspection and monitoring.

A long transmission line is an electrical transmission line that extends over a good-sized distance, typically carrying energy from one part of the grid to another. A long transmission line is an important part of the electrical system as it is made by using simple methods and is easy to understand.

In this article, we will be going through the long transmission line in a Power System, We will start our Article with the Definition of the Long Transmission Line, Then we will go through its Derivation and See its Different Types, At last, we will conclude our Article with its Advantages, Disadvantages and Some FAQs.
