Electrical substation now days the electrical power demand is increasing very rapidly. There is numerous electrical substation components like outgoing and incoming circuitry each of which having its circuit breakers isolators transformers and busbar system etc for the smooth functioning of the system.

Layout diagram of electrical power substation. Between the generation and distribution the voltage may vary through several substations. Incoming or power feeder connection 33kv incoming line power transformer connection via lighting arrestor busbar. The connection of the substation is divided as. The electricity substation is a network of electrical equipment which is connected in a structured way in order to supply electricity to end consumers. The substation is the part of an electrical supply system which transmits the high voltage from the generating substations to the local distribution networks. 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. The different types of layout for substation are explained below in details. Between the generating station and consumer electric power may flow through several substations at different voltage levels. Single line diagram33kv11kv substation this is the easy way to understand the working of substation. A substation engineer should have a good understanding of the electrical equipment and layout of hv power substation. Electrical bus system and electrical substation layout july 25 2018 february 24 2012 by electrical4u there are many different electrical bus system schemes available but selection of a particular scheme depends upon the system voltage position of substation in electrical power system flexibility needed in system and cost to be expensed.
Depending upon the availability of resources these stations are constructed. Go to content earthing and bonding. 3311kv substation layout duration. The function of an earthing and bonding system is to provide an earthing system connection to which transformer neutrals or earthing impedances may be connected in order to pass the maximum fault currentthe earthing system also ensures that no thermal or. Basic substation layout incoming sub transmission lines electric power path through substation outgoing distribution lines lightning arresters air break switches step down transformer distribution bus cutout switches oil circuit breaker voltage regulators metal clad switchgear control house. The single line diagram of the 33kv substation is depicted in the figure below.
The first step in designing a power substation is to design an earthing and bonding system. Voltage transformer connection for control and. For fulfilling these huge power demands the modern time requires creation of bigger and bigger power generating stations. Its also important to understand relationship between protection and the other equipment in the substations and the distribution system. These power generating stations may be hydro electric thermal or atomic. 220kv 66 kv electrical substation all.
