Manual Switching in Three-phase Circuits
Multi-pole loads can be switched directly in three-phase circuits up to a certain power rating. Suitable switching equipment is available but needs to be used in the correct way for each specific purpose. The development of circuits and the correct choice of switching elements and appliances are the key aspects handled in this educational unit. Topics include star-delta circuits, star-delta changeover circuits and polarity switching.
Training Concepts:
  • Turning off a three-phase induction motor with squirrel cage rotor
  • Star-delta circuit for a three-phase induction motor with squirrel cage rotor
  • Star-delta changeover circuit for a three-phase induction motor with squirrel cage rotor
  • Manual switching in three-phase circuits
  • Polarity switching with Dahlander three-phase induction motor
  • Polarity switching with three-phase induction motor featuring two different windings
