A coil symbol with a tap (usually close to one end, but not always).
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.
fixed taps and variable resistance
only single coil is use as a primary and secondary coil in a auto transformer.
basicaly the two inductors work as an autotransformer,providing a phase shift of 180 degree
I think you are confusing your terms. The term 'stator' (not 'stater') is used to describe the stationary part of a rotating machine (motor, generator), as opposed to the term 'rotor' which describes the rotating part. No part of an autotransformer is normally described as a 'stator'. An autotransformer has a laminated silicon-steel 'core', around which are placed 'windings'.
the power can flow either way through autotransformer (345/120 kV) ?
An autotransformer is a transformer where the primary and secondary are a single winding.

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.

cannot be used as an isolating transformer, because is has common winding.

"Auto" refers to the single winding used an auto transformer.
