Power distribution refers to the process of delivering electrical power from the generation source to end users through a network of transformers, substations, and distribution lines. It is classified into Low Voltage (LV), Medium Voltage (MV), and High Voltage (HV) systems based on the voltage levels used for transmission and distribution. Low Voltage (LV) systems operate at voltages typically below 1 kV and are used for residential, commercial, and small industrial applications. Household wiring and small office buildings usually operate on LV systems. Medium Voltage (MV) systems operate between 1 kV and 36 kV and are used for the distribution of power in industrial plants, large commercial buildings, and local utility grids. High Voltage (HV) systems operate at voltages above 36 kV and are primarily used for long-distance transmission of electricity from power plants to substations. HV systems minimize energy loss during transmission by reducing the current flow, which reduces heat loss in the transmission lines. Understanding the differences between LV, MV, and HV systems is essential for designing efficient and safe power distribution networks.
