What is Electrical Generator?

  Electrical Generator

  • An electrical generator is a machine which converts the mechanical energy into electrical energy.
  • The electrical energy, it could be DC power or AC power.
  • If the generator produces AC power then usually it called alternator.

  1. What is synchronous generator?
  2. What is prime mover in an alternator?
  3. What is Automatic Voltage regulator (AVR)?
  4. Alternator armature on stator vs on rotor.
  5. Why do turbo alternators use nonselient poles?
  6. What is the most severe fault on an alternator?
  7. The effect of prime mover failure in an alternator?
  8. What happens if we connect a capacitor to a generator load?
  9. How is the efficiency of an alternator affected by the load power factor?
  10. Why do we use hydrogen for cooling large turbo-alternators instead of air?
