Power transformers may be step-up or step-down. Distribution transformers are step-down. Isolation transformers are 1:1 ration Transformers. Matching transformers are used in electronic circuits for impedence matching purposes. Instrument transformers are used to measure high-voltage voltages and currents or to operate protective systems.

YNyn0
What is single phase autotransformer?
An autotransformer is a transformer with at least two windings where a part of one winding (the common winding) is shared between both primary and secondary outputs.
What does auto in autotransformer stands for?
"Auto" refers to the single winding used an auto transformer.
When a two winding transformer is connected as an autotransformer its efficiency under full load is?
remain same
How many windings does a auto-transformer have?
A true autotransformer consists of one, tapped, winding. For a step-down transformer, part of the winding is in series with the supply and the other part is common to both the supply and the load. For a step-up autotransformer, part of the winding is in series with the load, while the other part is common to both supply and load.But you can also use a mutual transformer as an autotransformer, by connecting the two windings in series and, then, described as above.

An autotransformer is a transformer with at least two windings where a part of one winding (the common winding) is shared between both primary and secondary outputs.
Why you not use auto transformer for distribution purpose?
because autotransformer used for both purpose step up and step down but dustrubution need step down in case of this autotransformer not used for dustrubtion purpouseAnswerBecause an autotransformer (not 'auto transformer') does not provide electrical isolation between the secondary and primary.
Which are the different types of winding connection in autotransformer?
fixed taps and variable resistance
What are disadvantages autotransformer?
cannot be used as an isolating transformer, because is has common winding.
What does auto in autotransformer stands for?
"Auto" refers to the single winding used an auto transformer.
