What is an Electrical Distribution System?

Electrical Distribution System refers to the section of the power system from the step-down distribution substation (high-voltage distribution substation) to the user end. It consists of a variety of distribution equipment (or components) and distribution facilities, and its main function is to transform voltage and directly distribute electric energy to end users.

Composition of Electrical Distribution System

Substation: The high-voltage electric energy transmitted to the substation is stepped down to low-voltage electric energy through facilities such as transformers for transmission to users.

‌Distribution network‌: The low-voltage electric energy of the substation is transmitted to the end user through distribution lines, switches, transformers and other facilities.

‌Transmission system‌: The power system that transmits electric energy from the power plant to the distribution substation usually adopts high-voltage transmission lines, including substations, substation equipment, transformers, high-voltage switchgear, high-voltage cables, etc.

Function of Electrical Distribution System

The main function of the Electrical Distribution System is to convert high-voltage electric energy into low-voltage electric energy and transmit the electric energy to users, providing users with stable, reliable and safe power supply. At the same time, the Electrical Distribution System also needs to have certain overload, short circuit and other fault protection capabilities to ensure the safe operation of the power system.

Application scenarios of Electrical Distribution Systems

The Electrical Distribution System is widely used by various types of end users, including households, enterprises, and institutions. Through reasonable voltage conversion and distribution, it ensures that all types of users can use electricity stably and safely.
