  • Electrical substation - Wikipedia

    A substation is a part of an electrical generation, transmission, and distribution system. Substations transform voltage from high to low, or the reverse, or perform any of several other important functions. Between the generating station and consumer, electric power may flow through several substations at different voltage levels. A substation may include transformers to change voltage levels between high transmission voltages and lower distribution voltages, or at the interconnection of two di

    Centralized Power Transmission and DistributionTransmission Lines and TowersDistribution SubstationsDistribution Substation ComponentsPower Distribution to Point of UseCentralized power distributionis the process of delivering electrical power that is generated at a large centralized location to customers. The power transmission and distribution system, from the power generation source to the customer’s loads, must be in good working order and properly maintained. See Figure 1. Figure 1.An electric utility produces electricity at a centralized generating station and transmits and distributes it to industrial, commercial, and residential customers through power lines, substations, and transformers. Power control, protection, transformation, transmission, distribution, and regulation must occur when electrical power is delivered to the customer. A centralized power transmission and distribution system commonly include the following parts: 1. Step-up transformers—The generated voltage is stepped up to transmission voltage level. The transmission voltage level is normally between 12.47 kV and 245 kV. 2. Generating station transmission lines —The 12.47...

    Jun 29, 2011 · Transmission and distribution are terms used commonly in connection with electricity. It is not just production that is important but how efficiently it is transmitted from the power plant to power sub stations and then finally to end consumers that makes up the entire system of generation to consumption. People commonly confuse between transmission and distribution and believe them to be synonyms but these terms are as different as chalk and cheese.

  • 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.

  • Power Generation, Transmission, Distribution and Safety

    What About Transmission lines?Power Plant SafetyStart with Safety to Improve Your Bottom LineAfter the generation of power, it is transported using transmission lines. These lines are constructed between substations that are located at power generation stations and they are either underground or overhead supported by towers. Transmission lines have high voltages and send out large amounts of electricity over considerable distances. After the electricity comes from the generating station, the transmitted voltage is stepped up to a range of 115,000 to 500,000 volts. However, when it gets into a transmission substation, the voltage is reduced to 46,000 to 115,000 volts. One of the main hazards during the transmission of power is electrocution. If your employees don’t use the necessary protective gear or maintain the proper distances, serious injuries and even death can result. Falls can also occur during the maintenance of overhead lines or while working from bucket trucks or poles. The transmission system is connected to customer’s equipment by a distribution system.
