AC Power Transmission refers to the process of delivering electrical energy over long distances using alternating current (AC). This method is preferred for its efficiency, as it allows for higher voltage levels, which reduces energy loss during transmission. Transformers are used to step up the voltage for long-distance travel and then step it down for safe use in homes and businesses. The main components of AC power transmission include transmission lines, substations, and transformers. These elements work together to ensure that electricity generated at power plants reaches consumers reliably. The widespread use of AC power is largely attributed to inventors like Nikola Tesla, who developed key technologies that made this system practical.
