Your question is incomplete -- what about the transformer?

?
Are you asking about a transformer turn to turn fault? Or if a transformer is shorted, does this turn into a fault? Please clarify the question.

Answer:
Transformer name plate shows the rating of the transformer...viz., operating frequency, rated current n voltage, output power in KVA, type of insulation used, tranformation turns ratio...
Additional Info: in addition to that, you would also find the percent impedance, size of the tank, tap configuration, and vector group. Here is photo of a typical power transformer nameplate: http://www.jcmiras.net/jcm2/p20.htm

Transformers are rated in KVA. (this is because the transformer is Unity power factor device i.e.. PF = 1)
AnswerThe selection of a transformer is determined by the apparent power of the load, expressed in volt amperes(V.A), the load current, and the line voltage of the supply. The transformer must be able to satisfy these requirements.
Transformers are not 'unity power factor' devices, which is precisely why their capacity is expressed in volt amperes, rather than in watts.

A: Absolutely a power transfer will have an internal loss of IR . for a power transformer the loss can be as much of 20% or more if other magnetics are involved like iron screw holding the lamination together. Usually brass is used to reduce that loss.

An isolation transformer is usually a ferromagnetic transformer.
The question needs to be framed more usefully.

because the copper is saved in the auto transformer
that is the ratio of weights of copper in auto transformer to normal transformer is (1-(1/a)) where a is transformer ratio

The difference between current transformer and potential transformer is that the secondary of a current transformer can not be open circuited while under service whereas that of the potential transformer an be open circuited without any damage to the transformer.

Transformer function is either to step-up or down the voltage. There is nothing like an ordinary transformer.

Variable transformer may also refer as auto transformer. We can vary the output voltage of the transformer. But in the ordinary transformers output voltage is already designed.

A transformer is fundamentally a set of coils; therefore, a transformer is an inductive load. However, by "transformer load", you seem to mean "the load that is connected to a transformer". Whether that load is inductive or capacitive depends mostly on what is hooked up to the transformer.

B.I.L. stands for Basic Impulse Level for the transformer. It should be on the faceplate of the transformer.

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 transformer can only increase or decrease
the voltage of an alternating current, and it is called step-up transformer or step-down transformer accordingly.
