GSM Based Three Phase Induction Motor Protection and Fault Detection System
Abstract Induction Motors are the most widely used motor for appliances, induction control and automation; hence they are robust, reliable and durable. Although Induction Motors are reliable, they are subjected to some undesirable stresses, causing faults resulting in failure. There are various types of faults that are encountered during operation of induction motor. Like electrical faults such as over/under voltage, over load, phase reversing, unbalanced voltage and single phasing. The rotor winding failure, stator winding failure and bearing faults are most occurring mechanical faults. The vibration of machine, external moisture, contamination and ambient temperature also affect the induction motor performance. So, in order to improve efficiency of induction motor all these faults has to be taken care of by reliable protection scheme. However, the control of machines is very risky and difficult when machine is on continuous duty. This project detects the faults in three phase in...
