Question
List out the advantages of the three-phase alternator.
✓
Answer
Three-phase system has many advantages over single-phase system, which is as follows:
- For a given dimension of the generator, a three-phase machine produces higher power output than a single-phase machine.
- For the same capacity, the three-phase alternator is smaller in size when compared to a single-phase alternator.
- Three-phase transmission system is cheaper. A relatively thinner wire is sufficient for transmission of three-phase power.
