Detection of Electrical Faults by the Time Frequency Approach

This paper argues that detection of electrical drives faults, especially the process of failure will be characterized, containing induction machines. First, the context of the study is keeping the faults which might occur in a rotating electrical body in mind, and the research in detection of fault. Second, the development of diagnostic of the machine will be shown. The signal processing in known operating phases (fixed speed), considering and locating malfunctions. In this context, we proposed a new approach for diagnosis electrical defects based on the value of rotor resistance as fixed for condition monitoring. MATLAB/SIMULINK simulation is used in this work.
