6. MICROCONTROLLER BASED PROTECTION OF INDUCTION MOTOR AGAINST

An essential component of contemporary power systems is the electrical protection of induction motors. Industries make extensive use of induction motors, which are extremely susceptible to anomalous circumstances like single phasing and overheating. Severe damage, insulation failure, and a decrease in motor life are possible outcomes of these situations. A microcontroller-based protective system is created to address these issues. Phase detecting circuits and an LM35 temperature sensor are used by the system to continually check the existence of all three phases and motor temperature. Real-time fault condi tion detection and input signal processing are handled by a PIC16F72 microcontroller. When any abnormal condition such as phase failure or high temperature is detected, the system automatically disconnects the motor using a relay. This improves system relia bility, reduces maintenance cost, and increases the lifespan of the motor.
