Want this question answered?
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.
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.
A three-phase transformer bank is often used in power stations because it is easier to construct and transport very large single-phase transformers, compared with constructing and transforming an equivalent-capacity three-phase transformer.
Transformer Inductance?
Voltage Tarnsformer transforms only voltage. While power transformer transforms both voltage and current.
It is a step down transformer which is used to supply the electrical power to the station transformers and the colony transformers
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.

ideal transformer is that which has no power losses.if any transformer transfer power to secondary without power loss then that call a ideal transformer

A power transformer is used to provide power (to your home, for example), an instrument transformer is used to measure voltage or current (for metering, for example).
You cannot 'change' the 'rated power' of a transformer except by changing the transformer for another one. You can, though, operate the transformer below its rated power or, for short periods of time, operate the transformer aboveits rated power.

rectifier transformer converts acinto dc.but,power transformer convert step up or step down ac energy without changing frequency
Low voltages are not 'combined into higher voltages' for transmission! The lower voltage (e.g. the voltage generated at a power station) is applied to the primary winding of a large power transformer, and the required higher transmission voltage then appears across the transformer's secondary winding. The magnitude of the secondary voltage is determined by the turns ratio of the transformer's windings.
