An isolation transformer is usually a ferromagnetic transformer. The question needs to be framed more usefully.
I suppose it could, but then it wouldn't be purely an isolation transformer. It would then be a isolation and either step up or step down transformer.
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.

a: 1:1 ratio its only purpose is to isolate
I suppose it could, but then it wouldn't be purely an isolation transformer. It would then be a isolation and either step up or step down transformer.
in isolation transformer earthing is not provide on secondary side but in ordinary transformer neutral of secondary side is earthedAnswerAn isolation transformer is a 1:1 ratio transformer; its function is to electrically isolate the secondary side from the primary side without changing the voltage. An example of an isolation transformer is the one used in a shaver socket.A distribution transformer is a step-down transformer, used within the electricity network's distribution system. An example of distribution transformer is a pole-mounted transformer, supplying low voltage to residences.(Of course, all mutual transformers provide electrical isolation between primary and secondary.)
You will have a 1:1 ratio isolation transformer.
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.
The function of an isolation transformer is to electrically-isolate the secondary circuit from the primary circuit, without changing the voltage levels. So, its secondary voltage will be the same as the primary voltage.
When the primary and secondary voltages are the same the transformer is being used for isolation. The secondary side will have galvanic isolation from the primary side. The purpose of the is to protect secondary load if a fault occurs on the primary side. The impedance of the transformer will limit the fault current on the secondary which should save equipment.
