Abstract :

This paper deal with protection of an induction motor against faults like over voltage, under voltage, single phasing ,voltage unbalance, over temperature. In this system 3 PT’s are connected to each phase of induction motor. The electrical signal is acquired by the ARM LPC2148 and 10 bit digital equivalent values of these electrical and temp signals are compared with the reference values by the means of software. The 10bit digital equivalent parameters are send to COM port of PC When any fault is detected ,the system activated relay and thus cuts the power supply to the induction motor. The corresponding faults are displaced on LCD display of ARM processor as well as the graphs plotted on console of a PC with the help of LAB VIEW 2014 software. LAB VIEW 2014 also stores a database file of the electrical signals along with graphs.
