Difference Between Overhead Lines and Underground Cables

The overhead lines and underground cables are methods used for the transmission and distribution of power in an electrical power system. The selection of overhead line or underground cable depends upon various factors like opera…

Vibration and Vibration Dampers in Transmission Line

The overhead transmission lines experience swinging in wind in the vertical plane. In addition to this, the overhead transmission line experiences two types of vibration. They are, Aeoline vibrations Galloping or Dancing vibratio…

What is Corona Loss? - Equation For Power Loss Due to Corona

Whenever corona occurs, due to electrostatic stress on the atmospheric air surrounding the conductors of the transmission line. The air becomes ionized and produces ions. These ions present in air experience a force upon them and…

Bewley's Lattice Diagram - Theory & Advantages

What is Bewley's Lattice Diagram? Consider a resistive load R L connected to a generator G having resistance R g through a transmission line of characteristic impedance Z c as shown in the future below. If a voltage or …

Transmission Line Parameters - What are they?

Generally, the electrical power is generated far away from the load centres. In order to transmit this generated power to the load centres transmission lines are used. The transmission line consists of conductors having a uniform…
