“…Comprehensive programs to maintain electrical equipment for peak performance have been recommended and implemented at various plants [1]. Detailed motor failure analysis has been completed; resulting in the identification of approximately 30% of failure causes being related to electrical failures [2]. A summary of the IEEE transaction entitled: "Report of Large Motor Reliability Survey of Industrial and Commercial Installations, Part I [3] included both the results of an IEEE survey and an EPRI survey.…”

Partial discharge monitoring is an effective on-line predictive maintenance test for MV motors, MV generators and MV switchgear at 4160 volt and above, as well as other electrical distribution equipment. The benefits of on-line testing allow for equipment analysis and diagnostics during normal production. Corrective actions can be planned and implemented, resulting in reduced unscheduled downtime. An understanding of the theory related to partial discharge, and the relationship to early detection of insulation deterioration is required to properly evaluate this predictive maintenance tool. This paper will present a theory to promote the understanding of partial discharge technology, as well as various implementation and measurement techniques that have evolved in the industry. Data interpretation, corrective actions and application to electrical distribution equipment will also be reviewed.

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.

“…These signs and some of their secondary signs can be used as indexes for fault diagnosis of the motor. So far, for detection of these indexes, various methods have been proposed which cover different aspects of science and technology [3]. Deviation of magnetic potential vector and asymmetrical magnetic flux distribution has been used to diagnose the broken rotor bars [4].…”

One of the most frequently used fault detection methods for induction motor is the current signature analysis. This technique depends upon locating by finite element method and analysis of specific harmonic components in the line current produced by unique rotating flux components caused by faults such as broken rotor bars. The motor current signature analysis method can detect these problems at an early stage and thus avoid secondary damage and complete failure of the motor.
