Abstract – Induction motormonitoring is a fast budding online technology for finding embryonic faults. Aswired connectivity is hazardous for human being, the wireless monitoring systempreferred to avoid faults occurs at the moment of operation. A low pricedsystem for monitoring the parameters such as temperature, current, voltage andspeed of Induction Motor as well as controlling the system with wireless ZigBeetechnology described in this paper. This system uses four sensors to measurethe respective parameters of Induction Motor. These measured parameters aresensed by ZigBee coordinator.
ZigBee coordinator transfers all these data tothe ZigBee End Device which is connected to computer through USB to TTL. Byusing the computer interfacing with ZigBee module motor can start and stop andsystem get sheltered. Key Words: Induction Motor, ZigBee Module, Current, Voltage, Speed, Temperature. 1. INTRODUCTIONIn industrial sector,single phase and three phase power system widely used for domestic, commercialand industrial purpose. Induction motors are easy to design and available atcheap cost, low maintenance, easy to repair and reliable.
Although, it isreliable some inexpedient stresses occur in it which results in the failure ofinduction motor. Therefore, parameters monitoring of an induction motor are useto expose the initial faults. The necessity formonitoring has increased because of the widespread use of automation andultimately mitigates the human efforts. This system is used to correct the machineproblems before the occurrence of failure. Digital monitoring and classicalmonitoring are two monitoring techniques. A wired system which is combination ofelectrical and mechanical monitoring tools is classical monitoring technique.
It is also called as traditional monitoring technique. Digital monitoring hasvarious techniques such as microcontroller based protection system but in thissystem result is not displayed on the screen. In PLC based protection systemdata not stored as well as not exhibit. Digital system is less costly andreduces time for revealing of defects. ZigBee wireless technology is preferredtoday because it overcomes all drawbacks. ZigBee acquire less power consumptionability with low cost, greater litheness and huge range.
