Abstract: A system and method for detecting stator inter-turn fault in induction machines includes receiving a time series data of a stator current using a plurality of current sensors connected to a stator of the induction machine, determining first and second signature time series data of stator current using fundamental components and harmonic components of the stator current, determining first and second scaled signatures using an Unbalance Factor, determining a discrimination factor, and detecting a stator inter-turn fault when the discrimination factor is greater than a predetermined stator inter-turn fault threshold value.
