Among the most noticeable root causes of improper performance in power transformers, internal short circuit faults can be noted and if not quickly be identified and addressed in the accepted time interval, irrecoverable damages such as interruption or even collapse of the network connected to the power transformer would happen. In this contribution, three-phase transformer behaviors under magne...

Service replication distributes an application over many processes for tolerating faults, attacks, and misbehavior among a subset of the processes. With the recent interest in blockchain technologies, distributed execution of one logical application has become a prominent topic. The established statemachine replication paradigm inherently requires the application to be deterministic. This paper...

In this paper, grid disturbances like asymmetrical sag and swell faults in phase-A are analyzed for the grid connected DFIG. The dynamic behavior of DFIG is compared and tabulated with results using state error compensators like PI, PI with resonant (PIR) and internal model control (IMC) on rotor side converter (RSC). The RSC is designed analytically with enhanced field oriented control (EFOC) ...

Faults in electrical machines can vary in severity and affect different parts of the machine. This study focuses on various kinds of short-circuits on the terminal side of a generic 20 kW surface mounted permanent magnet synchronous generator and how successive faults affect the performance of the machine. The study was conducted with the commercially available finite element method software CO...

<span>The main aim of this work is to analyze the input current waveform for a single-phase induction capacitor-run motor (SIMCR) detect faults. Internal and external faults were applied SIMCR was measured. An armature (broken rotor bar) bearing SIMCR. A microcontroller used record signal MATLAB software it with different types fault varying load operations. Various values running capacit...

Frequency Response Analysis (FRA) technique has been recognized by worldwide utilities as a matured technology to assess the mechanical integrity of power transformers. While some industrial critical assets such induction motors have same construction principle transformers, application FRA not yet fully explored. This paper presents analogical experimental studies for on transformers and motor...

Radio Frequency Identification (RFID) is a rapidly upcoming technology that has become more and more important also in securityrelated applications. In this article, we discuss the impact of faults on this kind of devices. We have analyzed conventional passive RFID tags from different vendors operating in the High Frequency (HF) and Ultra-High Frequency (UHF) band. First, we consider faults tha...

This paper describes a new methodology to inject transient and permanent faults in digital systems. For this purpose, the simulation based fault injector VERIFY (VHDL-based Evaluation of Reliability by Injecting Faults efficientlY) has been developed, which allows fault injection at several abstraction levels of a digital system. The combined approach of injection and analysis of the results en...

This paper presents an IDDQ-based test strategy for detecting bridging faults in the logic resources of reprogrammable Field Programmable Gate Arrays (FPGAs). The proposed approach utilizes the programmability of the Configurable Logic Blocks (CLBs) to achieve 100 percent coverage of IDDQ-testable bridging faults. We use a hieararchical approach for generating tests and configurations. At the c...
