Questions & Step-by-Step Solutions

What is the main advantage of using a three-phase transformer over three single-phase transformers?
  • Step 1: Understand what a three-phase transformer is. It is a single unit that can handle three phases of electricity at once.
  • Step 2: Know what single-phase transformers are. They are separate units that handle one phase of electricity each.
  • Step 3: Compare the efficiency. A three-phase transformer can transfer power more efficiently than three single-phase transformers working together.
  • Step 4: Consider the cost. Buying one three-phase transformer is usually cheaper than buying three separate single-phase transformers.
  • Step 5: Think about space. A three-phase transformer takes up less space than three single-phase transformers, making it more compact.
