High voltage transmission refers to the process of transporting electrical energy over long distances using high voltage power lines. This method is essential for delivering electricity from power plants to homes and businesses, as it reduces energy loss that occurs when electricity travels through wires. By increasing the voltage, the current can be decreased, which minimizes heat loss due to resistance in the conductors. The infrastructure for high voltage transmission includes transformers, substations, and transmission lines. Transformers are used to step up the voltage for long-distance travel and then step it down for safe use in homes. This system is crucial for maintaining a reliable and efficient electricity supply across vast regions.
