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.

A mulit tap ballast is in fact an auto transformer.
there is nothing like a balanced and unbalanced transformer.
What is the difference between an ordinary transformer and resonant coupling energy transfer?
A transformer changes the amperage and / or voltage. It literally "Transforms" electrical energy. A ballast is like a capacitor. Think of a ballast as a short-term battery. It stores power then releases it as needed. A common example of a ballast is on fluorescent lights. Initially, a fluorescent light needs a big blast of energy to excite the gas molecules into emitting photons (light). Then it only needs a small amount of energy to keep the gas molecules in an excited state. However, that power has to be of consistent amperage and voltage. The ballast is designed to do that. The electrical ballast stores energy in the same way that a water ballast stores water for stability. Because the electrical ballast stores far more power than the device it regulates requires, it too provides a kind of electrical stability. That's why you often see a fluorescent light flicker or "lose stability" when the ballast starts to go bad. A transformer transforms voltage and amperage up or down. A ballast provides a stabile power supply.
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

Yes, there is an excitation current that flows through the primary side of the transformer which is located in the magnetic ballast's casing.
