Question 17Electricity & Electronics - Assistant Engineer

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.
