In this paper a model representing a group of three-phase induction motors , with terminal power-factor correcting capacitors, following disconnection of the group with its terminal capacitors as one unit from the supply , is derived. From this model the transient behavior of the motors of the group and the interaction between them, following supply disconnection is investigated , and the effect of the terminal capacitors on the transient behavior of each motor of the group , regarding terminal voltage , stator currents , airgap powers , is shown.
