Induction machines play a important role in industry and there is a demand for their reliable and safe operation. Different failures occurs in induction machines gives excessive down times and generate large losses in term, and this motivates the condition monitoring of induction motors. The condition monitoring includes taking measurements on three phase induction motor when it is operating in order to detect faults reducing both unexpected failures and maintenance costs. Condition monitoring of induction motors reduce the cost of maintenance and the risk of unexpected failures. In condition monitoring maintenance, one does not schedule maintenance or machine replacement based on previous records or statistical estimates of machine failure. The system for condition monitoring uses sensors for measurements of different parameter while a machine is in operating condition to determine if a fault exists. The project is to monitor the operating conditions of three-phase Induction motors. This system is based on a low-cost electronic device that can acquire and pre-process current, voltages and temperatures and speed transmit processed key-information related to the motor operation conditions using ZIGBEE wireless technology.

This system present an embedded system integrated into a WSN for online parameters such as power, speed, temperature, voltage and current monitoring in induction motors. We use different sensors for the purpose of sensing the parameters. The calculations for estimating the targeted values are done locally and then transmitted to a monitoring base unit through an IEEE 802.15.4 WSN. Results are displayed on LCD. The system is a combination of advanced techniques and plant management process, aiming for goal through technical means. Wireless sensor network is used to transmit data collected from the machine to the base station. The total system gives an efficient mechanism for the measurement & monitoring of the parameters of the induction motor without interrupting the actual working of the system. In this study, a parameter monitoring system for induction motors based on Zigbee protocol is achieved and tested successfully. The system developed is capable to perform such operations as running the motor though RF, measuring, monitoring and controlling the most parameters of the motor like phase currents, phase voltages, temperature, speed. The on line parameter monitoring system eliminates the costly installations of communication cables. The system developed can be used for not only industrial applications but also educational purposes.
