Stator Turn-to-Turn Fault Detection of Induction Motor by Non-Invasive Method Using Generalized Regression Neural Network
Condition monitoring and protection methods based on the analysis of the machine's current are widely used according to non-invasive characteristics of current transformers. It should be noted that, these sensors are installed by default in the machine control center. On the other hand, condition monitoring based on mathematical methods has been proposed in literature. However, they are model b...
متن کاملMotor Current Signature Analysis and Its Applications in Induction Motor Fault Diagnosis
--The Motor Current Signature Analysis (MCSA) is considered the most popular fault detection method now a day because it can easily detect the common machine fault such as turn to turn short ckt, cracked /broken rotor bars, bearing deterioration etc. The present paper discusses the fundamentals of Motor Current Signature Analysis (MCSA) plus condition monitoring of the induction motor using MCS...
متن کاملCondition monitoring methods, failure identification and analysis for Induction machines
Induction motors are a critical component of many industrial processes and are frequently integrated in commercially available equipment and industrial processes. The studies of induction motor behavior during abnormal conditions, and the possibility to diagnose different types of faults have been a challenging topic for many electrical machine researchers. The Motor Current Signature Analysis ...
متن کاملRotor Faults Detection in Induction Motor by Wavelet Analysis
ABSTRACT Motor current signature analysis has been successfully used for fault diagnosis in induction motors. However, this method does not always achieve good results when the speed or the load torque is not constant, because this cause variation on the motor slip and fast Fourier transform problems appear due to non-stationary signal. This paper experimentally describes the effects of rotor b...
متن کاملShort Winding Fault Detection Using Park’s Vector
The subject of on-line detection of short winding fault in three-phase induction motors is discussed, and a noninvasive approach, based on the computer-aided monitoring of the stator current Park’s Vector, is introduced. The park's vector representation is obtained using Virtual instrument. The Virtual Instrument is obtained by programming in Labview software. The laboratory tests were conducte...
