    1. Generating station: At the generating station, electricity is produced using a power source such as a coal-fired power plant, hydroelectric dam, or wind farm. The voltage level at the generating station is typically high, in the range of 11 kV to 33 kV.
    2. Transmission: The electricity produced at the generating station is transmitted over long distances to the distribution system using high-voltage transmission lines. The voltage level at this stage is also typically high, in the range of 132 kV to 765 kV.
    3. Substation: At the substation, the voltage of the transmitted electricity is reduced to a level that is suitable for distribution to the consumer. The voltage level at the substation is typically medium, in the range of 11 kV to 33 kV.
    4. Distribution: The electricity is then distributed to the consumer via medium-voltage distribution lines. The voltage level at this stage is typically medium, in the range of 4 kV to 33 kV.
    5. Service entrance: At the service entrance, the voltage of the electricity is reduced to a level that is safe for use in the consumer’s premises. The voltage level at the service entrance is typically low, in the range of 120 V to 480 V.
    6. Consumer premises: The electricity is then distributed throughout the consumer’s premises using low-voltage wiring. The voltage level at this stage is typically low, in the range of 120 V to 240 V.
