FAULT DETECTION OF INDUCTION MOTORS

Abstract

In this work described method of fault detection of induction motors. Induction motors are broadly utilized in numerous mechanical applications. Subsequently, it is exceptionally imperative to monitor and detect any faults during their operation in arrange to alarm the administrators so that potential issues can be avoided before they happen. In common, a fault within the acceptance motor causes it to induce hot amid its operation. This paper presents a developed protection method algorithm that uses unbalanced power components and simulates the overall design based on the Matlab Simulink. Three-phase voltage and current data are observed first, followed by signs of unbalanced power, according to the digital relay safety algorithm. The relay then uses a negative sequence reactive power sign to decide if the fault is internal or external. A negative sign for negative sequence reactive power indicates a fault inside the motor, while a positive sign indicates a fault outside the motor.
