Analysis and Real-Time Implementation of Power Line Disturbances Test in Three Phase Induction Motor

The main objective of the paper is to analyze and utilize the grid emulator to compare the behavior of the three-phase induction motor to voltage sags (dips). This work presents an examination of voltage sags and a short interruption immunity test of a three-phase induction motor to examine the resistance of the machine against the voltage sags and short interruptions. This happens broadly in low voltage mains. Voltage sag is an issue influencing electrical characteristics. The negative torque instigated during fault causes a reduction in speed of the machine, influences to three-stage voltage sag on the three- phase induction machine. A three-phase squirrel cage induction motor of 0.75KW/415V is tested with balancing three-phase separate voltage sag of various depths and magnitude. A similar investigation is finished regarding the waveforms of RMS current, power, and voltage sag. An investigation of voltage sag is contrasted and the attributes of a three-phase induction machine running in the ordinary condition. By using MATLAB/Simulink analyzed the performance of induction machine under-voltage swell and harmonics distortion.
