Delta-Delta Transformer
A type of three-phase transformer connection where both the primary and secondary windings are connected in a delta configuration.
Turns Ratio
The ratio of the number of turns in the primary winding to the number of turns in the secondary winding of a transformer, determining its voltage transformation characteristics.
Primary Voltage
The voltage at the input of a transformer or any primary side of an electrical system.
- Ascertain the turns ratio and evaluate its impact on the voltage across diverse transformer setups.

Final Answer :
C
Explanation :
The turns ratio of a transformer is determined by the ratio of the primary voltage to the secondary voltage. For a delta-delta transformer with a primary voltage of 7200 V and a secondary voltage of 360 V, the turns ratio is 7200/360 = 20:1.
