What type of transformer is needed before the electricity from the Power Station is sent into the National Grid?

From the Generator station, the voltage is sent to a step up transformer. Transmission at higher voltages is used to over come line loss over the miles of transmission.

Why need to vacuum in transformer chamber before filling transformer oil and how long need to vacuum?
we need vacuum to remove moisture from tank
Does electrical power lines pass through step down transformer or step up transformer before entering you home?
A step-down transformer supplies electricity to your home. The values of voltage involved depend on the electrical standards in your country. For example, in the UK, the primary nominal voltage is typically 11 kV, and the secondary nominal voltage is 400/230 V (three phase) or 230 V (single phase). Incidentally, the power lines do not 'pass through' a transformer. They terminate at the transformer's terminals. Energy is transferred from the primary to the secondary through mutual induction. The primary and secondary windings are electrically isolated from each other.
Does the drained transformer oil come under the category of Used Oil or Waste oil?
It depends on the local and national regulations. There is not a single correct answer for this question. In many areas, used transformer oil must be tested for PCB (poly chlorinated biphenyl) compounds before it can be mixed with other oils or burned. Today, advanced recycling and processing facilities can improve the characteristics of used transformer oils to meet the specifications set for new oils.
What kind of transformer is used to change the voltage of electric current in transmission lines before it enters houses in a neighborhood?
It's called a 'distribution transformer', as opposed to a 'power transformer' which is used in the transmission and primary-distribution electrical systems.
Why transformer is used before conected any semiconductor device?
because it is necessary to provide an over load protection ,surge protection,etc....hence an transformer is used...( particularly isolated transformers)
What percentage of homes had a supply of electricity before the national grid?
1%
What are different types of transforms?
A small list of Transformers1. Distribution Transformers2. Padmount Transformers3. Station Transformers4. Station Transformers Various specific electrical application designs require a variety of transformer types. Although they all share the basic characteristic transformer principles, they are customize in construction or electrical properties for certain installation requirements or circuit conditions.Autotransformer: Transformer in which part of the winding is common to both primary and secondary circuits.Capacitor voltage transformer: Transformer in which capacitor divider is used to reduce high voltage before application to the primary winding.Distribution transformer, power transformer: International standards make a distinction in terms of distribution transformers being used to distribute energy from transmission lines and networks for local consumption and power transformers being used to transfer electric energy between the generator and distribution primary circuits.Phase angle regulating transformer: A specialized transformer used to control the flow of real power on three-phase electricity transmission networks.Scott-T transformer: Transformer used for phase transformation from three-phase to two-phase and vice versa.Polyphase transformer: Any transformer with more than one phase.Grounding transformer: Transformer used for grounding three-phase circuits to create a neutral in a three wire system, using a wye-delta transformer,[85][90] or more commonly, a zigzag grounding winding.Leakage transformer: Transformer that has loosely coupled windings.Resonant transformer: Transformer that uses resonance to generate a high secondary voltage.Audio transformer: Transformer used in audio equipment.Output transformer: Transformer used to match the output of a valve amplifier to its load.Instrument transformer: Potential or current transformer used to accurately and safely represent voltage, current or phase position of high voltage or high power circuits.Pulse transformer: Specialized small-signal transformer used to transmit digital signaling while providing electrical isolation.

Why are power lines that travel long distances often run at high voltages?
The simple answer is that voltage drops over distance. To avoid this loss, power companies distribute electricity in kilovolts (kV). This is then stepped down to domestic voltage (220-240V in Europe, 110V in USA etc) at a local sub-station (basically a large transformer), before reaching your home.
Do they have Burger King transformer toy?
I think they did before.
How good is the asus transformer tablet?
The asus transformer is not a good tablet. There have been many studies that show how the asus transformer tablet causes cancer. I would read more about the asus transformer tablet and the risks before taking this product.
How do you say station in french?
The same as before station.

Where does the electricity power station get its electricity?
An electricity power station gets its electricity by spinning electricity turbines. A turbine, or generator, is a magnet spinning inside a coil of copper wire. The turbine is driven by wind, water, or steam from geothermal, nuclear, or from burning fossil fuels (coal, oil and natural gas), biomass or renewable bio-methane.A:This sounds like a silly question, because the power station makes electricity. However if it is shutdown to start with, the auxiliaries on the station need some power before it can be started. This would normally be imported from the grid connections, so that necessary pumps, instruments, computers, etc can be powered up ready for start up. On nuclear stations there are always also diesel generators which can cope with requirements for in house power in the event of losing the grid connection. A:All power plants, not just nuclear, have a means to generate auxiliary electricity to get the plant up and running. These are usually diesel generators that are started by batteries.
