This paper presents an AdaBoost method based on RVM (Relevance Vector Machine) to detect and locate an interturn short circuit fault in the stator windings of IM (Induction Machine). This method is achieved through constructing an Adaboost combined with a weak RVM multiclassifier based on a binary tree...

Stator interturn faults are one of the most common faults occurring in induction motors. Early detection of interturn short circuit is important to reduce repair costs. Axial leakage monitoring, zero-sequence components, negative sequence current, and motor current signature analysis have been used for fault detection in early states. In the paper, the instantaneous power signature analysis tec...

In this paper, Wavelet based ANFIS for finding inter turn fault of generator is proposed. The detector uniquely responds to the winding inter turn fault with remarkably high sensitivity. Discrimination of different percentage of winding affected by inter turn fault is provided via ANFIS having an Eight dimensional input vector. This input vector is obtained from features extracted from DWT of i...

This paper presents a parametric low differential order model, suitable for mathematically analysis for Induction Machines with faulty stator. An adaptive Kalman filter is proposed for recursively estimating the states and parameters of continuous–time model with discrete measurements for fault detection ends. Typical motor faults as interturn short circuit and increased winding resistance ...

Interturn short circuits are a common fault of permanent magnet synchronous motors (PMSMs). This paper proposes new method to detect the interturn short-circuit (ISCF) five-phase PMSM. The first takes command voltage and measured current each phase winding as original signal then obtains delay orthogonal via Hilbert transform. Then, generalized instantaneous reactive power can be calculated fro...

Abstract This paper presents the robust detection of interturn short circuit fault double redundant permanent magnet synchronous motor. In static coordinate system and dq-axis system, mathematical model state is established. Further, residual signal current caused by turn-to-turn predicted using Luenberger observer. Next, marker phase are obtained processing signal. Finally, processor performs ...

Transformer protection is critical issue in power system as the issue lies in the accurate and rapid discrimination of magnetizing inrush current from internal fault current. Artificial neural network has been proposed and has demonstrated the capability of solving the transformer monitoring and fault detection problem using an inexpensive, reliable, and noninvasive procedure. This paper gives ...

According to the transfer impedance getting from distributed parameter model,we analyse the influences of magnetic conductivity , the number of turns ,capacitance to the shield and interturn capacitance on the high frequency characteristic of Rogowski coil through theories and simulations. Simulation shows that there are a series of zeros in high frequency band, but on the whole, the high frequ...
