Electrical power distribution is the process of delivering electricity from a power generation source to end users, such as homes, businesses, and industries. This system involves a network of substations, transformers, and distribution lines that reduce the high voltage from transmission systems to a lower, usable voltage. Distribution networks are typically divided into primary (high voltage) and secondary (low voltage) systems, ensuring reliable and efficient delivery of electricity. The process also includes protective devices to manage and isolate faults, ensuring continuous and safe power supply to consumers.
