Protection of Three Phase Induction Motor using PIC18F4431

Three phase induction motors are widely used in many industrial applications.As these operate on electric supply and have mechanical moving parts,they often face electrical and mechanical faults. the electrical faults like overvoltage, overcurrent, overload, single phasing are have to be taken care of. The PIC microcontroller 18F4431 is provided with 8 PWM generators to create and control PWM to control voltage and speed of motor. with the help of this advanced chip we can protect this three phase induction motor
