Questions & Step-by-Step Solutions

In a three-phase transformer, how many primary and secondary windings are there?
  • Step 1: Understand what a three-phase transformer is. It is a type of transformer that uses three phases of electricity.
  • Step 2: Know that a transformer has two main parts: primary windings and secondary windings.
  • Step 3: In a three-phase transformer, there are three phases of electricity, which means there are three primary windings.
  • Step 4: Similarly, there are three secondary windings to match the three primary windings.
  • Step 5: Therefore, a three-phase transformer has a total of 3 primary windings and 3 secondary windings.
