An electrical system is a network that generates, transmits, and distributes electrical energy to power homes, businesses, and industries. It typically includes components such as generators, transformers, and power lines that work together to deliver electricity from power plants to end users. These systems can be divided into three main parts: generation, where electricity is produced; transmission, which involves high-voltage power lines that carry electricity over long distances; and distribution, where the voltage is lowered for safe use in homes and buildings. Proper maintenance and safety measures are essential for efficient operation.
