What is the equipment used in GSS?
Substations generally have switching, protection and control equipment, and transformers. In a large substation, circuit breakers are used to interrupt any short circuits or overload currents that may occur on the network.
What is the purpose of grid station?
The main task of a grid station is to transfer the electricity to very far distances where the users are located. They also interconnect all the power plants of a country so that if one power plant fails, you still receive the electricity uninterrupted.
How is a substation designed?
Substations are the points in the power network where transmission lines and distribution feeders are connected together through circuit breakers or switches via busbars and transformers. The first step in designing a power substation is to design an earthing and bonding system.
What is grid substation?
A National Grid substation is a large installation where 275 kV and 400 kV overhead power lines or underground cables are switched and where electricity is transformed to 132 kV for distribution to surrounding areas.
What is the meaning of grid substation?
Ans) GRID STATION: The word grid means combination. Combination or interconnection of various power system elements such as generating stations, transmission lines, distribution lines etc. SUBSTATION: Substation is a place where transmission and distribution lines are connected together.
What is a grid substation?
What are the benefits of the national grid?
What are the benefits of the National Grid?
- Power stations can be based in less populous and remote areas of the country meaning pollution can be kept away from major cities.
- If one power station needs maintenance, consumers can still be supplied from others around the country.
Which of the following points must be kept in view while designing a layout of substation?
While laying out an underground sub-station, the following points must be kept in view: (i) The size of the station should be as minimum as possible. (ii) There should be reasonable access for both equipment and personnel. (iii) There should be provision for emergency lighting and protection against fire.
