Intelligent Condition Monitoring and Protection for Electrical
Chalermchat Manop1* Siriporn Hengkiatisak2 and
Electric motors used in industry are an important part of production process and concerning about
energy conserving. In this paper, we present a condition monitoring system for industrial electric motors. The
system has been designed to monitor and to display operating conditions of the running motor in order to keep the
machine operated efficiently. Significant signals of motor are measured, recorded and then processed to find out any
kind of faults using artificial neural network. The software is designed and implemented with graphical user
interface (GUI) in MATLAB program for interfacing with on-line data acquisition (DAQ) card. Experimental
results show that the computer-based protection method developed, if any fault was observed during any online
operation of the motor, a warning message appeared on the PC s monitor screen, and then, the motor was stopped.
The test was successful in detecting the faults and protection of motor.
