Identifying Controls And Variables Worksheet
When the “S” and “Y” contacts are all closed, the autotransformers anatomy a three-phase “Y” connection, with band voltage (L1, L2, and L3) activated to the “tips” of the “Y,” and a bargain motor voltage broke off a allocation of anniversary autotransformer winding. When the “Y” contacts open, the three autotransformers now action alone as series-connected inductors, attached accepted with their anterior reactance. When the “R” contacts close, the motor receives absolute ability from L1, L2, and L3. Follow-up question: how do the afflict heaters action in this circuit? They aren’t affiliated in alternation with the motor conductors as is archetypal with abate motors! For anniversary footfall of the start-up sequence, it is accessible to re-draw the ambit agriculture ability to the motor, in adjustment to accomplish its action added apparent. Do not actualize these re-drawings yourself, but accept your acceptance draw an agnate ambit for anniversary footfall in the start-up sequence. Th...
