Several papers have been written on the response of directly connected induction motors or adjustable speed drive (ASD) connected motors to unbalanced and balanced voltage sags caused by faults on the power system. This paper will detail the interaction between the motors and drives and the supplying distribution system both during and after the voltage sag. In addition, the system effect of transferring the loads during the sag to an alternate feed with solid-state switching is evaluated. The Electro-Magnetic Transients Program (EMTP) was used for the analysis.
