Question 17Electricity/Electronics - Assistant Engineer70% to pass
Which of the listed figures shown in the illustration represents a three phase transformer connected in a wye-wye configuration? Illustration EL-0084
AI Explanation
The correct answer is B.
The illustration EL-0084 shows a three-phase transformer connected in a wye-wye configuration, which is represented by figure 2.
In a wye-wye configuration, the primary and secondary windings of the transformer are both connected in a wye (Y) configuration. This means that the three-phase windings are connected with a common neutral point, forming a Y-shaped connection.
The other options, A, C, and D, represent different transformer configurations, such as delta-delta or delta-wye, which do not match the wye-wye configuration described in the question.
