Power transmission refers to the movement of energy from its place of generation to a location where it is used to perform work.
What are the main types of power transmission?
The main types include mechanical, electrical, hydraulic, and pneumatic transmission.
What is a transmission line?
A transmission line is a conductor or conductors designed to carry electricity over large distances from power plants to substations.
Why is voltage increased for long-distance power transmission?
Voltage is increased to reduce energy losses by lowering the current through the lines.
What are transformers and their role in power transmission?
Transformers are devices that transfer electrical energy between circuits using electromagnetic induction, primarily used to increase or decrease voltage levels.
