Why transmission at high voltage is preferred than at low voltage?

Question

Accepted Answer

Transmission at high voltage is preferred due to lower power losses and reduced infrastructure costs.

High voltage transmission reduces power losses during transmission.
Lower current at high voltage reduces resistive losses in transmission lines.
High voltage transmission allows for longer transmission distances without significant power losses.
Reduced power losses result in higher efficiency and lower energy costs.
High voltage transmission requires less infrastructure, such as fewer substations and transformers.
Examples of high voltage transmission systems include HVDC (High Voltage Direct Current) transmission and long-distance power transmission lines.
