“…The effects of voltage unbalance on induction motors has been studied using different methodologies such as finite element analysis, experimental motor tests, dq0 transformation approach, harmonic distortion studies, thermal models, vibration analysis [5,[11][12][13][14] etc. According to [12], the major focus of a number of research studies on voltage unbalance has been centred on voltage magnitude unbalance [15][16][17][18] without any consideration for the effects of phase angle unbalance or preferably supply phase shift on the induction motor. This paper explores the significance of phase shift on induction motor performance using the phase frame approach for motor component analysis [9].…”

The impact of supply phase shift on the three phase induction motor operation

The performance of a three-phase induction motor operating under supply unbalance conditions has been the focus of many research works using various methods. Most of the studies have focused majorly on voltage magnitude unbalance without due analysis to determine the effect of deviations in the supply phase angle from the 120° phase to phase displacement. This research investigates the significance of supply phase shift on the performance of a three-phase induction motor by applying a novel phase shift unbalance definition to the zero, negative and positive sequence components model of the motor. The test results reveal that when both phase angle shift and voltage magnitude unbalance occur simultaneously during motor operation the effect of the phase shift dominates over the effects of the voltage magnitude unbalance. This study shows that phase angle unbalance has a severe consequence on three phase motor performance.

This paper is focused on the measurement and analysis of supply voltage quality in low voltage industrial power systems in Estonia. A practical method for analysis of supply voltage quality parameters, implementing stochastic theory, is discussed. Measurement results of supply voltage quality parameters-voltage magnitude, voltage events, harmonics, flicker and unbalance in industrial 0.4 kV power systems of Estonia-are shown.
