Is transformer an amplifier?
No. In an amplifier, Power Out > Power in. In a transformer Power Out ~= Power In (minus internal losses). An AC generator is more like an amplifier than a transformer.
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.
What is single phase ac generator?
It's an electrical generator converting mechanical power into electrical power. The electrical power comes out in the form of single-phase alternating current.
How variable speed generator works and its specification?
First you have to understand how a generator works. Basically the excitation voltage is what varies according to generator output. Usually on a power source that has a inconsistant rpm, the excitation voltage will vary similar to a govenor in order to hold the generator output constant.
Which is to consider in sizing generator kva or kw ratins?
the unit of generators power is KVA becoze the kva is the power that contain the active power (KW) and the reactive power mean that the name plate of any generator must contain the rated kva of it (like the transformer P (KW) = P (kva) * cos fi P (KW) = V I cos fi for single phase P (KVA) = V I when cos fi closed to 1 this will increase the useful power that exit from the generator or transformer with my pleasure
Block diagram of thermal power station?

Why generating station capacity mentioned in KW even though alternator rating is in KVA?
In generator station the power which produced is real power the real power to me mentioned in its's factor so it is mentioned as KW or MW. In transformer there is no effect of change the power factor (ie:cos,phi) and the power which transfer do not changes its frequency. so, in Transformer and generator it is mentioned as KVA.

Can a transformer be used to power a deep fridge from a generator?
You power "type" must match. Most likely your generator should be able to have the fridge plug directly in, but you may indeed need a transformer to step the voltage up or down.
How does a automatic transfer switch work?
The load have deference two feeder like transformer &generator when the power of transformer shutdown the load get power from second feeder generatoraoto
Which part of a power station is like a dynamo in your bicycle?
The generator
What is tie transformer?
It is a step down transformer which is used to supply the electrical power to the station transformers and the colony transformers
What are examples of mechanical to electrical energy?
A steam turbine/generator in a power station, a small gasoline powered generator, or a 12v alternator in your car driven by the engine.
What is the machine in a power station that changes kinetic energy into electrical energy?
for instance generator, crusher, boiler, coal
How is electricity produced at a power station?
In a coal-fired power station, a boiler burns coal to produce steam. The steam makes a turbine spin. The turbine drives an electricity generator. The electricity from the generator is converted to a higher voltage by a transformer. This higher voltage is to enable transmission over long power lines without losing too much energy. When it comes to reach our homes, it is then converted back into lower voltage by other transformers. Nuclear power stations are similar - instead of a coal-fired boiler, a nuclear reactor creates the steam. Wind turbines use the blades to turn the generator.
Describe 6 difference method of producing electricity?
Hydro electricity (Water power) Diesel generator Coal fired power station Nuclear power station Gas fired power station Wind turbine generators.
