In the electricity supply industry, the term, power transformer, is used to describe Transformers that are used in the electricity transmission system (i.e. for the UK, at 400/275/132/33-kV levels), as opposed to distribution transformers that are used in the electricity distribution systems (i.e. for the UK, at 11 kV/400-230 V levels). They vary tremendously in physical size, according to their operating voltages and power ratings -typically expressed in megavolt amperes.
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
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 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
Transformer Inductance?
B.I.L. stands for Basic Impulse Level for the transformer. It should be on the faceplate of the transformer.
It isn't! A transformer operating at no load has a very low power factor.
Adams Power Plant Transformer House was created in 1895.
The inductance of the transformer is much higher than the resistance of the transformer, resulting in very low real power losses (in watts), but some reactive power (vars).
Knowing the power rating of a transformer will help an operator use the transformer within its design limitations with regard to heating of the windings and their insulation.
