Abstract :
The paper deals with the investigation of the effects of three-phase voltage dips on the induction motors. The experimental set-up comprises a dip generator, a three-phase analyzer and a control system. As model, a three-phase squirrel cage induction motor of 1.5 kW / 0.4 kV is tested with balanced three-phase individual voltage dips of different magnitudes and durations, and of different rectangular and non-rectangular forms. A comparative analysis is done regarding the wave form and shape of rms three-phase currents and voltage dips curves. The decreasing of current and power of induction motor was correlated with voltage dip magnitudes. The experimental determinations of the effects of balanced three-phase voltage dips are compared with characteristics of induction motor operating in normal conditions.
