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.
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.
autostep down transformer
cannot be used as an isolating transformer, because is has common winding.
fixed taps and variable resistance
"Auto" refers to the single winding used an auto transformer.
A coil symbol with a tap (usually close to one end, but not always).
