The present demand in
the industry is for high performance electric drives that are capable of
achieving speed commands accurately. Control methods have had to reach higher
levels of sophistication accordingly. Induction motors, with their advantages
in terms of size, cost and efficiency, are best suited to meet these growing
needs. In costly systems, maintenance and protection are especially essential
in the prevention of system breakdowns and catastrophes it is now possible to
utilize wavelet principles to efficiently diagnose and protect industrial
induction motors. In this paper, we investigate the use of the wavelet in the
fault detection of vector controlled induction motors, detection of the broken
rotor bar and stator short winding faults as well as the verification of
wavelet fault detection models using MATLAB. Finally, two approaches for the
protection of induction motor are examined. The first uses the Automatic Gain
Control (AGC) to compensate the voltage of the induction motor to maintain
satisfactory operation. The second halts operation when the fault severity
becomes high. Without delving into excessively detailed results, we analyze the
output relevant to wavelet detection and diagnosis
