  • Electric power distribution - Wikipedia

    Electric power distribution is the final stage in the delivery of electric power; it carries electricity from the transmission system to individual consumers. Distribution substations connect to the transmission system and lower the transmission voltage to medium voltage ranging between 2 kV and 35 kV with the use of transformers. Primary distribution lines carry this medium voltage power to distribution transformers located near the customerpremises. Distribution transformers again lower the

  • Electric power transmission - Wikipedia

    For other uses, see Electric transmission (disambiguation). Electric power transmission is the bulk movement of electrical energy from a generating site, such as a power plant, to an electrical substation. The interconnected lines which facilitate this movement are known as a transmission network. This is distinct from the local wiring between high-voltage substations and customers, which is typically referred to as electric power distribution.

  • Electricity Delivery and its Environmental Impacts | Energy

    About Electricity DeliveryElectricity Delivery in The United StatesEnvironmental Impacts of Electricity DeliveryAfter a centralized power plantgenerates electricity, the electricity must be delivered to the end-user. This delivery happens in three steps: 1. Transmission. Centralized power plants produce high-voltage electricity to facilitate the transmission of the electricity over long distances and lessen the amount of electricity lost to friction in the wires. High-voltage transmission lines typically carry the electricity to a substation. 2. Substation.Substations are used to condition electricity as it moves through the grid. Substations can include switching, protection, and control equipment; capacitors; voltage regulators; and transformers. Substations can either “step down” or “step up” high- or low-voltage electricity to prepare it for further transmission or distribution. 3. Distribution. The distribution portion of the electric grid comprises lower voltage power lines that deliver electricity to end-users. Distribution networks tend to span shorter distances and involve delivery o...

    Why Is Alternating Current Used For Transmission? AC is used for transmission because transformers can step it up to high voltage for long distance, and down to low voltage for local distribution and use. What Is Corona? The phenomenon of violet glow, hissing noise and production of ozone gas in an overhead transmission line is known as Corona. What Is Skin Effect? The tendency of alternating current to concentrate near the surface of a conductor is known as Skin Effect. Why Is Voltage Stepped Up Before Transmission? Voltage is stepped up before transmission due to the following reasons: Reduces volume of conductor material.

  • What is distribution substation and its main components? | EEP

    Supply Line. Distribution substation is connected to a sub-transmission system via at least one supply line, which is often called a primary feeder. However, it is typical for a distribution substation to be supplied by two or more supply lines to increase reliability of the power supply in case one supply line is disconnected. Transformers. Transformers “step down” supply line voltage to distribution level voltage. See Figure 3 below. Distribution substation usually employs three-phase transformers. Busbars. Busbars (also called buses) can be found throughout the entire power system, from generation to industrial plants to electrical distribution boards. Switchgear. Switchgear (Figure 6) is a general term covering primary switching and interrupting devices together with its control and regulating equipment.
