Fault detection and protection of three phase induction motor

Induction motors are widely used in industries.some electric faults may cause malfunctioning of it, so protection of it against these incipient faults is very necessary. This monograph refers to an approach of protection of motor using micro-controller.It emphasizes on PIC 18F4431 family controller to detect the faults and protect them. some simulink modelling and simulations are done to find the tolerable limit values.
