What is a transformer foundation?
Transformers Foundation is the unified voice representing the denim industry and its ideas for positive change.
How do you create a substation?
Conduct planning meetings for the new power substation. Perform load flow power studies. Determine the substation size and total footprint required (with equipment), including transmission right of way (ROW). Determine substation configuration (Single Bus, Main/Transfer Bus, Ring Bus, etc.).
What is control room in substation?
The various supervision, control and protection functions are performed in the substation control room. The relays, protection and control panels are installed in the controlled room.
What is substation construction?
Substations receive high-voltage power from stations and grids via the overhead lines of transmission systems. It’s here, at the substation, where voltage levels are transformed before continuing on through the power network.
What does a transformer do in a substation?
A substation may include transformers to change voltage levels between high transmission voltages and lower distribution voltages, or at the interconnection of two different transmission voltages.
What is substation designing?
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 an electrical control room?
ELECTRICAL CONTROL ROOM- An electrical control room is a room or space in a building dedicated to electrical equipment. Its size is usually proportional to the size of the building; large buildings may have a main electrical room and subsidiary electrical rooms.
What is control room function?
A control room’s purpose is production control, and serves as a central space where a large physical facility or physically dispersed service can be monitored and controlled.
What are the three main parts of a substation?
There are three main types of substation: transmission, distribution, and collector.
- Transmission. A transmission substation connects transmission lines, generally when all the lines concerned have the same level of voltage.
- Distribution.
- Collector.
What is the main purpose of a substation?
The purpose of a substation is to ‘step down’ high voltage electricity from the transmission system to lower voltage electricity so it can be easily supplied to homes and businesses through our distribution lines.
Which transformer is used in substation step up or step down?
Transformers “step up” or “step down” voltage according to the ratios of primary to secondary wire turns. A transformer designed to increase the voltage from primary to secondary is called a step-up transformer. A transformer designed to reduce the voltage from primary to secondary is called a step-down transformer.
What type of transformer is used in substation?
Substation transformers are most often offered with one of 3 different fluids: Mineral oil or silicone transformer oil. Primary voltages of a substation transformer usually ranges from 2.4 kV to 69 kV in 225 through 20,000 kVA sizes, but 600 volt through 35 kV secondary voltage ratings are also available.
What is involved in building a substation?
Preparation of a key plan which should show the location of all components of a substation and their interconnections, as well as steel structures, control house, fire walls, driveways, fence and property line. Selection and ordering of equipment, which is usually done in a utility company by a designated group of equipment experts.
How to build a substation or retrofit the old one?
Building a new substation or retrofitting the old one is a complex process full of design and engineering tasks to be worked on. The main steps in substation design and engineering are as follows: Step 1 – switching system. Selection of a substation switching system: ring bus, breaker-and-a-half, etc. based on reliability requirements.
Are electrical rooms part of your building design?
Electrical rooms and mechanical, electrical, and plumbing (MEP) spaces are often an afterthought when it comes to building design and planning, either relegated to locations that are left over or deemed undesirable for other planning purposes.
How do you isolate a substation from the grid?
Open all circuit 2 disconnectors. Connect all circuit 2 earthing switches. Open circuit 1 circuit breaker. Open all circuit 1 disconnectors. Connect circuit 1 transformer earthing switches. After this you can found your substation (Bus I, II) isolated from the grid receiving no power, exporting no power so it’s completely shut down.
