An open delta transformer is assembled from two 50 kVA transformers. The output power of the open delta is _____.
A) 100 kVA
B) 86.6 kVA
C) 150 kVA
D) 157.7 kVA

Question

Quizplus · Accepted Answer

The output power of an open delta transformer configuration is approximately 86.6% of the combined rating of the two transformers. Therefore, for two 50 kVA transformers, the output power is 0.866 * (50 kVA + 50 kVA) = 86.6 kVA.
