A delta-delta transformer has a primary voltage of 7200 V and a secondary voltage of 360 V. What is the turns ratio?
A) 11.55:1
B) 15:11.55
C) 20:1
D) 51:20

Question

Quizplus · Accepted Answer

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.
