What Is an Electrical Substation? Key Functions and Components Explained

An electrical substation is a critical component of the power transmission and distribution system. Its primary function is to receive electricity from high-voltage transmission lines and deliver it at lower voltages suitable for end users, such as homes, businesses, and other consumers. The operati
