Terminology • The terminology used for describing devices and Architectures varies significantly across vendors as well as with age and size of a particular substation B. Substations and switchgear inherently operate at high voltages. It typically also comprises switchgear and other components. The parts of substation are equipped with auto-switch technology and can handle distinct kinds of low and high voltage transmissions. It is a distribution sub-station placed overhead on a pole. We are manufacturers of Electrical Substation Equipment or Substation Components like all types of High Voltage Switches & Fuses. Pole-Mounted Sub-Station: 1. power = transformer represents a transformer device, as a . UNESCO – EOLSS SAMPLE CHAPTERS ELECTRICAL ENERGY SYSTEMS - Components and Substations for Electrical Transmission and Distribution Systems - B. E. Kirichenko, S.D. Electrical Substation is one of the most important parts in electrical engineering. 11 KV Substation. Standard Bentley Substation content placement tools now show content from Components Center. The range includes connectors, clamps and hardware for tubular aluminium busbars in both bolted and welded solutions as requirements dictate. A – Building Grounding Substation Details A key requirement is that power supply through this substation must not be interrupted as a result of a fault or the maintenance of the circuit breakers in this substation. One-Half Breaker Configuration. C. Three strands of barbed wire above a 6-foot-high fence. 31 1501 Rev. 2. Electric substation with dischargers, vacuum interrupters and high voltage transformers against the background of a blue sky. Different Digital Components of Substations-2020 By Engr. Meaning of Substations 2. which can be used to send electricity from one place to another and all these are connected to the substation. This is because a transformer can be bought in any one of the following configurations 120VAC 1-ph, 240VAC 1-ph, 208V 3-ph wye, 240V 3-ph delta, etc. In single line representation of substation the electrical components such as power transformers, incoming and outgoing lines, bus-bars, switching and protecting equipments, are represented by standard symbols and their interconnections between them are shown by lines. It protects the substation equipment from transient high voltage and also limits the duration and amplitude of the flow of current. This course is designed to provide an in-depth study to aid skilled qualified substation maintenance technicians in the safe performance of substation components preventive maintenance. The transformer and other equipment are Transcribed image text: i) A large step-down substation, which steps down from 400 kV to 132 kV, is to be designed. There are also Components scattered throughout the map, and we’ll include the locations of any that are along the path, too. Lizunov, N. N. Tikhodeev ©Encyclopedia of Life Support Systems (EOLSS) in 1990. In this post, I will discuss some main 15 Essential basic components that really required in a substation. Substation Components PLP’s substation component product range caters for all standard busbar tube diameters, including 80, 100, 125, 160, and 200mm with wall sections from 4 to 12mm. Electrical Substation components. 31 1502 – Communication Site Grounding Typical Grounding 34. Figure 4 Secondary Substation Components . A transformer substation adopts the state-of-the-art substation equipment layout idea. Electrical Substation Components: The substation for electricity has various equipment like an isolator, bus bar, power transformer, etc. Maintain a record of the most current readings and observations to ensure that all parts, from the main transformer, cooling/heating systems, bushings, and tap changer tanks, to every switch and connection, comply with industry regular standards. Some of the important components of substation … Busbars. It is a strip or bar of copper, brass or aluminium that conducts electricity within a switchboard of a substation.Surge or Lightning Arresters. It discharges the over voltage surges to earth and protects the equipment insulation from switching surges and lightning surges.Isolators or disconnecting switches. ...Earth Switch. ...Circuit Breaker. ...More items... In this article, I am listing the main electrical substation components for … Substations may be described by their voltage class, their applications within the power system, the method used to insulate most connections, and by the style and materials of the structures used. Switchyards and substations are important components of this system. The main role of the substation is to transform the electricity generated by the turbines from 33 kilovolts (kV) up to 150 kV. These are generally known as substations. High-voltage equipment - vacuum switches and insulators on metal supports on metal supports. Therefore, the look is impressive and the compact substation size was optimized to be 1/10 of the same capacity power substation. 6! Isolators are provided for isolation from line parts for the … It is the cheapest form of substation as it does not involve any building work. Substation Design Volume VIII Site & Foundation Design Instructor: Lee Layton, P.E 2015 PDH Online | PDH Center 5272 Meadow Estates Drive Fairfax, VA 22030-6658 Phone & Fax: 703-988-0088 www.PDHonline.org www.PDHcenter.com Figure 7: A typical auxiliary AC system in a substation. It typically also comprises switchgear and other components. Electrical substation components are essential for substation installation. 3.Free maintenance due to the reliable performance. A unit substation is factory built and tested, then shipped in modules that are bolted together at the site. Array Cables. A substation has many components such as step-up transformers, step-down transformers, disconnecting switches, circuit breakers, voltage transformers current transformers, and surge arrestors. Control building. Switches for safely disconnecting and grounding lines are used when personnel are working on the lines. The substation interconnects power lines from different parts of the system and also protects all the equipment in the power system. Electrical substations are the most complex components of modern transmission and distribution systems. There are multiple ways to install the substation (basically, in the form of indoor and outdoor types). You can analyze data from the power system software or directly from relays and identify if there is a ground fault, phase-to-phase fault, etc. Hitachi ABB Power Grids has the unique ability to design, supply and install the entire electrical system from the grid substation to the miniature circuit breaker at the server, utilizing reliable and robust systems and products. Therefore, its trapping is of utmost importance. Utility components and substation hardware fittings from the USA require a precision approach to manufacturing. NFPA Standard 70E provides additional specific guidance on procedures and the level of personal protective equipment required when inspecting substations. Components of a Substation. Because of the SF6 gas in the sealed tank, so the gas insulated substation components work in stable condition, it will be much less fault than the air-insulated substation. United States Department of Agriculture Rural Utilities Service RUS Bulletin 1724E-300 Issued June 2001 Design Guide for Rural Substations A substation has many components such as step-up transformers, step-down transformers, disconnecting switches, circuit breakers, voltage transformers current transformers, and surge arrestors.
