Assessment of disturbed voltage supply effects on steady-state performance of an induction motor [PDF]

, 2020
An electric power system is usually exposed to unequal and variable loads across its three phases, which leads to voltage unbalance and variation, making the three-phase voltages asymmetrical in nature at the distribution end.
