Induction motor supply voltage variations for distribution system faults

Abstract

The present paper deals with a characterization of supply voltage variations on induction motors when transient faults occur on distribution feeders or busbars. The main parameters that can qualify the voltage perturbation are presented and discussed both on the theoretical point of view and with example of application. The test network chosen shows the effectiveness of the index that represents the quality of the motor supply voltage when network faults occur.
