• The proposed method utilizes the direct features of electric arc. Our detects incipient fault considering minority and momentary features. Fault data are obtained from both simulation experimental recorded data. guarantees simplicity in implementation, speed, accuracy. It distinguishes transients such as inductive load change capacitor switching. discriminates harmonic load. Incipient faults ...

Advanced telemetry systems are being developed to collect and archive hundreds of system performance, throughput, quality-of-service (QoS), and physical variables for the purpose of enhancing the reliability, availability, serviceability, scalability, and security of business-critical enterprise computing servers. SAS software was chosen for this project because of the language's powerful codin...

In cooperation with the major propulsion engine manufacturers, the authors are developing and demonstrating a unique very high frequency (VHF) vibration monitoring system that integrates various vibroacoustic data with intelligent feature extraction and fault isolation algorithms to effectively assess engine gearbox and generator health. The system is capable of reporting on the early detection...

Three-phase induction motors are widely used in different applications the industry due to their robustness, low cost, and reliability. Untimely identification correct diagnosis of incipient faults reduce cost improve maintenance management these machines. This paper explores a new method for robust classification rotor failures three-phase (MITs) connected directly electrical network, operatin...

• Identifying abnormality and determining time of disturbance occurrence. Discriminating the incipient fault from capacitive switching sudden load variations. harmonic loads considering arc models. The faults which mainly occur due to electric occurrence in power cables with insulation defects are hardly detectable by conventional protective relays, over can develop into a permanent system. Emp...

Fault-tolerant control methods have been extensively researched over the last 10 years in the context of chemical process control applications, and provide a natural framework for integrating process monitoring and control aspects in a way that not only fault detection and isolation but also control system reconfiguration is achieved in the event of a process or actuator fault. But almost all t...

In this paper the incipient fault detection problem in induction machine stator-winding is considered. The problem is solved using a new technique of change point detection in time series, based on a two-step formulation. The first step consists of a fuzzy clustering to transform the initial data, with arbitrary distribution, into a new one that can be approximated by a beta distribution. The f...

The integrity of the wiring in the electric power system of an aircraft is vital to its safe operation. To ensure the wiring integrity, it must be tested to determine if any incipient defects exist. For this purpose, joint time-frequency domain reflectometry (JTFDR) has proven to be effective on shielded, coaxial cable. This paper demonstrates the ability of JTFDR to also effectively detect and...

Dissolved gas analysis (DGA) is one of the regular routine tests accepted by worldwide utilities to detect power transformer incipient faults. While DGA measurement has fully matured since development offline and online sensors, interpretation results still calls for advanced approaches automate standardize process. Current industry practice relies on various techniques that are reported be inc...

The periodical transient impulses caused by localized faults are sensitive and important characteristic information for rotating machinery fault diagnosis. However, it is very difficult to accurately extract transient impulses at the incipient fault stage because the fault impulse features are rather weak and always corrupted by heavy background noise. In this paper, a new transient impulse ext...
