Textbook Question
Chapter 29, Problem 1RQ
How many transformers are needed to make an open-delta connection?
Expert Solution & Answer
To determine
The number of transformers needed to make an open delta connection.
Answer to Problem 1RQ
Two transformers are needed to make an open delta connection.
Explanation of Solution
The open delta connection is used when the amount of three-phase power needed is not excessive. From the figure it can be seen that the open-delta transformer connection can be made with only two transformers. The total output power is 86.6% of the sum of the power rating of the two transformers when an open-delta connection is used.
