Fault Detection and Protection Fault Detection and Protection of Induction Motors Usingof Induction Motors UsingSensorsSensors

ABSTRACTABSTRACT

Protection of an induction motor (IM) Protection of an induction motor (IM) against possible problems, suchas against possible problems, suchas overvoltage, over current, overload, overvoltage, over current, overload, over temperature, and under over temperature, and under voltage,occurring in the course of its voltage,occurring in the course of its operation is very important, because operation is very important, because it is used intensively in industry as an it is used intensively in industry as an actuator.actuator.

IMs can be protected using someIMs can be protected using some components, such as timers, components, such as timers,

contactors, voltage, and current contactors, voltage, and current relaysrelays
