Question

Which of the following is not correct w.r.t. delta connection?

• A. Needed in almost all motors
• B. There is no neutral
• C. Four wires are required
• D. Used in transmission to distant places

Answer 1

The correct option is C

Four wires are required

Delta connection is desirable for transmission to distant places because only three wires are required here. There is no neutral in the delta connection. Four wires are required for star connection.
In large and small-scale industries, the primary and secondary coils are in delta winding.
