Fault detection and protection of induction motor using fuzzy logic

Abstract

This paper deals with fault diagnosis & Protection of induction Motor. A various types of faults are occurred in the I.M such as over voltage, under voltage, over current, single phasing. The proposed system detects the various types of faults by monitoring stator current of induction motor. To predict and protect the type of fault occurs in induction motorA fuzzy logic with PIC microcontroller is used. Experimental results shows fuzzy based fault detection and protection method which provides higher accuracy with safe environment also it reduces failure risk of I.M.
