Sensors for Fault Detection and Protection of Induction Motors

PROJECT TITLE :

Fault Detection and Protection of Induction Motors Using Sensors

ABSTRACT:

Because an induction motor (IM) is used extensively in industry as an actuator, its protection against probable faults, such as overvoltage, overcurrent, overload, overtemperature, and undervoltage, is crucial. Some components, like as timers, contactors, voltage, and current relays, can be used to safeguard IMs. The classical method, which is relatively simple and uses mechanical dynamic parts, is known as this method. Most mechanical components have been eliminated by computer and programmable integrated circuit (PIC) based protective mechanisms. An ADC card is required for computer-based protection; on the other hand, the electrical parameters measured by PICs cannot be viewed using this approach of computer-based protection. As part of this work, a programmable logic controller (PLC)-based protection solution was developed for IMs. All contactors, timers, relays, and the conversion card are eliminated in this manner. A computer monitors the voltages, currents and speeds of the motor, along with any issues that may have arisen in the system, to alert the operator. The PLC-based protection approach developed is less expensive, more accurate, and delivers a safer and more visually appealing environment than the traditional, computer, and PIC-based systems.
