A mulit tap ballast is in fact an auto transformer.
An isolation transformer is usually a ferromagnetic transformer. The question needs to be framed more usefully.
The difference between current transformer and potential transformer is that the secondary of a current transformer can not be open circuited while under service whereas that of the potential transformer an be open circuited without any damage to the transformer.

Variable transformer may also refer as auto transformer. We can vary the output voltage of the transformer. But in the ordinary transformers output voltage is already designed.

there is nothing like a balanced and unbalanced transformer.
Both are same. This is an instrument transformer used for metering & protections.
The 3 kVA transformer will weigh double the 1.5 kVA transformer.

potential transformer is to maser and protection purpose the ivt is used for synchronicing purpose

A power transformer is used to provide power (to your home, for example), an instrument transformer is used to measure voltage or current (for metering, for example).
Control transformer used only for control supply 110,220, 24,12V AC. But Potential transformer used voltage measurement purpose.
A step-up transformer increases voltage, while a step-down transformer decreases voltage.
