HEALTH MONITORING AND PROTECTION SYSTEM FOR INDUCTION MOTOR

Electrical Engineering

Our idea is to continuously evaluate the health of Induction Motor. By doing so, we would be able to have warning before any damage due to fault.This paper is to study an improvement in protection of Induction Motor. It solves the problem of damaging of Induction Motor due to unnoticed fault. Condition monitoring can be explained as the continuous evaluation of the health of the plant and instrument throughout its working duration. It is important to detect faults while they are developing which is called incipient failure detection. Incipient failure detection can provide safe operating environment. In many applications, these motors are operated under environmental stresses, such as high ambient temperature, high moisture, etc, which could lead to motor malfunction. Malfunction of these motors leads to not only high repair expense, but also extraordinary financial loss due to unexpected downtime. Therefore, reliable monitoring and protection for MV motors is of great value to avoid catastrophic unscheduled downtime. By using the condition monitoring we can give the warning, well in advance to correct the situation and avoid shutdown. This can result in minimum downtime and optimum maintenance schedule. Condition monitoring and fault diagnostic technique can help the operator to be ready with the spare parts before occurring the shutdown situation and hence reduce outgoing.
