This article presents a comparison of the operation of three-phase induction motor under normal conditions, compared to a low of motor. In that case, if there is no load, and if there is a load of 25, 50, 75 and 100 percent the way Knicks harmonic of a fault that occurs in Australia. Derived from data of pressure levels measured at each phase to the spectral analysis of the flow from the motor. How to convert Phu ye quick service (Fast Fourier Transform: FFT) research found that can detect failure to run out a winding short circuit in motor induction station Nanaimo 3-phase. By analyzing the flow of each phase is different compared to normal state. Which found that the power of the State in the event of a short circuit coils. There will be greater than in a normal condition, which causes the motor's performance decreased.
