In a standard delta-connected three-phase system without a neutral, there is no neutral conductor.

In a standard delta-connected three-phase system without a neutral, there is no neutral conductor.

• A. There is no neutral
• B. The grounded conductor is used as neutral
• C. A dedicated ground conductor acts as neutral
• D. The neutral is provided by a separate winding

Answer: (A)

In a delta-connected three-phase system, the three windings form a closed loop with no common connection point where all three windings meet. That absence of a central node means there is no neutral conductor supplied by the source. A neutral exists only with a wye (star) connection, where the windings share a common point. Grounding is separate from neutral and does not create a neutral path for normal current in a delta setup. If a neutral is needed, it must come from a transformer or a wye-connected side, not from a standard delta. That’s why the statement “there is no neutral” is correct.
