SMART PROTECTION FOR INDUCTION MOTORS: FAULT MONITORING AT ITS BEST

Abstract

In the realm of electrical motors, a diverse array of faults can manifest, falling broadly into two categories: external and internal. External faults may stem from environmental conditions or other extraneous factors, whereas internal faults are typically rooted in circuit-related issues. This paper delves into the realm of fault mitigation, with a primary focus on ensuring the protection of motors against the perils of overheating, overvoltage, and under-voltage.

Overheating, a common motor issue, often arises from overloading. To ensure continuous monitoring of temperature, the DS1820 sensor is deployed, allowing for precise temperature measurement. Furthermore, well-defined upper and lower voltage thresholds are established to guarantee the motor's seamless operation. Regulating temperature and voltage levels within the motor is entrusted to the ARDUINO Nano controller, a sophisticated component known for its adeptness at temperature sensing and voltage monitoring. In the event that the sensors detect values that veer beyond the predefined operational limits, they promptly communicate with the ATmega328P microcontroller.

The ATmega328P, a robust 8-bit microcontroller boasting a 32KB Flash memory, belongs to the esteemed ATmega AVR MCUs series, developed by Atmel. It serves as the central decision-making hub for the motor's protective actions.
