Question on: JSS2 Basic technology - Introduction to Power Systems

Transmission lines are essential in power systems as they transport electricity from power plants to substations and ultimately to consumers. High-voltage transmission lines are preferred for long-distance transport because they minimise energy losses during transmission. By transmitting electricity at high voltages, the amount of current needed to deliver a specific amount of power is reduced, thereby reducing resistive losses along the transmission lines and ensuring efficient energy transport.
