Since, transfformer is a Static device (ie. no moving parts in it) hence it is the most efficient machines ever made by man.
However, in rotating machines there are various losses like friction and windage, losses in commutator etc.
So, yes, Transformers are highly efficient devices.
A step up transformer converts low voltage,high amperage current to a high voltage,low amperage current. It requires large diameter wire to carry the high amperage in the primary coil.
A stp-down transformer steps voltage down from a high value to a low value. Transformers only work with AC.
Through the use of the basic transformer voltage equation.
The step up transformer is used to change the voltage from high to low or low to high voltage by eitherincreasing the number of inding or reducing the number of winding in the transformer,thus when the winding reduced on side of primary winding and ingreasing number of winding on secondary side it means the transformer should be step up transfo0rmer,and when the you increase number of turnsin primary side and reduce turned on secondary sidde the transformer said to be step down transformer
its efficiency will decresed.
if the transformer is distributing transformer then we shoud have to give more prefer to the high volatage to reduce losses if we distibute power at low volage there is more current which causes more losses and in hv system there is high volage and low is current so the losses are also low
The "all day" efficiency of a transformer is defined as the ratio of energy out/energy in for a given all day cycle.
A high efficiency machine will produce more of what is it that you want with the same power as the low efficiency one. In other words, for a low efficiency machine do as much as a high efficiency one, you have to give it more power (energy).
The efficiency of a simple transformer is limited by resistive loss in the wiring, and by hysteresis (magnet related) losses in the transformer core. You may limit the resistance loss by using superconductors at very low temperatures. But not practical for most situations. (Yet!)

Low
the efficiency is maximum in a transformer when no load loss is equal to load loss.
An air gap in the magnetic path of a transformer increases the reluctance of the magnetic circuit, reducing the magnetic flux and efficiency of the transformer. This can lead to increased losses, lower power transfer efficiency, and potentially impact the regulation of the transformer. It is generally preferred to have a low-reluctance magnetic path for optimal transformer performance.

A step up transformer converts low voltage,high amperage current to a high voltage,low amperage current. It requires large diameter wire to carry the high amperage in the primary coil.
When selecting a low voltage transformer for a 300 watt application, key considerations include ensuring the transformer can handle the wattage capacity, selecting the appropriate voltage rating, considering the efficiency and size of the transformer, and ensuring compatibility with the electrical system and safety standards.
the inductive load which is generally use in high voltage transmission line known as transformer. the transformer transform the high voltage to low voltage.
