REAL TIME MOTOR FAULT DETECTION AND PROTECTION SYSTEM

In this paper, an ESP32 microcontroller is used to develop and build an Automatic Motor Protection System. A 1 HP single-phase induction motor is shielded by the system from a number of electrical and environmental issues, including as overcurrent, overvoltage, undervo ltage, and exposure to rain or moisture. The system uses a voltage sensor and a current sensor (ACS712) to continually check the motor's electrical characteristics. In order to identify moisture that might lead to short circuits or insulation breakdown, a rain sensor is incorporated. The ESP32 initiates a relay to cut off the motor from the power source in order to prevent damage when any parameter beyond the safe operating threshold. LEDs act as visible failure indications, and a 20x4 LCD display shows the current state of every parameter under observation. The suggested method is appropriate for industrial and agricultural applications as it improves motor dependability, lowers maintenance costs, and does away with the need for human monitoring.
