Manual Switching in Three-phase Circuits (230 V)
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:
  • Switching a squirrel-cage three-phase induction motor on and off
  • Star-delta connection of a squirrel-cage three-phase induction motor
  • Star-delta reversing circuit for a squirrel-cage three-phase induction motor
  • Pole reversal with Dahlander three-phase induction motor
  • Pole reversal with a three-phase induction motor with two separate windings
