  • Difference Between High, Medium and Low Voltages

    Factories that require medium or high voltage supply from the electric utility can have a dedicated sub-station. These substations step down voltages levels and distribute to buildings throughout the property. However, not all factories require high or medium voltages. Some require low voltages of 240, 480, or 600 VAC from utilities.
