Questions & Step-by-Step Solutions

In a three-phase transformer, how many sets of windings are required?
  • Step 1: Understand that a three-phase transformer is used to transfer electrical energy in three phases.
  • Step 2: Recognize that each phase of the transformer needs its own winding to function properly.
  • Step 3: Since there are three phases (Phase A, Phase B, and Phase C), you will need one winding for each phase.
  • Step 4: Conclude that a total of three sets of windings are required for a three-phase transformer.
