A: The only way can be possible if the transformer is an isolation type. Yes, you can put the input into the secondary side. This will create a step-up transformer.
A single-phase transformer works with a single-phase supply, while a 3-phase transformer is used with a 3-phase supply. A single-phase transformer has 2 wires on the primary and secondary (ignoring taps) while a 3-phase tansformer has 3 or 4 wires on the primary and secondary.
First find the ratio of the transformer. 6600/220 volts. Second find the secondary current, I = W/E, 99000/220. Third divide the secondary current by the transformer ratio. The answer will be the primary current. To check your answer (W (or VA) = V x A) multiply the primary current times the primary voltage and the secondary current times the secondary voltage and they should both equal the transformer's kVA.
This 480-v three-phase transformer probably has a 208-v three-phase secondary which has 120 v from each line to neutral. In that case the primary current is 0.433 times as much as the secondary current, so 100 amps in the secondary means 43.3 amps in the primary.
The phase relationship between the primary voltage and the secondary voltage of a transformer is 180 degrees (typically) on single phase transformers. If working with three phase transformers, a zero phase shift is often used in Y/Y grounded transformers. If the transformer is wired Delta / Wye, the phase shift will be 30 degrees. I've seen transformers with a phase shift of 150 as well (quite abnormal, but it exists!) due to the starring and a delta / wye configuration. If you are looking at a transformer phasor diagram, this will show the phase shift between primary or secondary (three phase transformers). For single phase, there should be a drawing showing polarity markings - what goes in the polarity marking on the primary comes out on the secondary polarity marking.

The voltage phase shift between primary and secondary connections in a transformer is 180 electrical degrees.
it has three primary windings & three secondary windings.
Maintaining a phase displacement between the primary and secondary windings of a transformer allows for the effective transfer of power from the primary to the secondary circuit. This phase difference ensures that the magnetic flux induced in the primary winding can generate a voltage in the secondary winding, enabling power to be transmitted efficiently and accurately between the two circuits.

For a transformer, the turns ratio always applies between its primary and secondary windings. So the turns ratio for a three-phase transformer is the ratio of primary to secondary phase voltages, not between line voltages.
The # of windings in a transformer are based on the primary and secondary voltages the transformer is rated for not the way the windings are connected.
primary winding flux links with secondary winding produses voltage across the secondary winding
