Arc Fault Detection Through Model Reference Estimation
In most arc fault circuit breakers, arc detection is accomplished through the signature analysis of remotely sensed branch currents, with high frequency spectral components being indicative of arcing. This paper presents an alternative approach based upon system identification. A model is assumed for the load on the distribution bus. This model is updated continuously by comparing measured volt...
متن کاملSeries Arc Fault Detection Algorithm Based on Autoregressive Bispectrum Analysis
Arc fault is one of the most critical reasons for electrical fires. Due to the diversity, randomness and concealment of arc faults in low-voltage circuits, it is difficult for general methods to protect all loads from series arc faults. From the analysis of many series arc faults, a large number of high frequency signals generated in circuits are found. These signals are easily affected by Gaus...
متن کاملArc Fault Detector
The subject of arc fault detection and circuit interruption has gained a lot of attention in recent years, particularly in the aviation industry. This is primarily due to a spate of in-flight fires which have been linked to faulty electrical systems and wiring on aircraft. Typical causes of faults are wiring chafing, dust build up and moisture [1][2]. Until recently, aircraft circuit breakers, ...
متن کاملSignal Injection as a Fault Detection Technique
Double frequency tests are used for evaluating stator windings and analyzing the temperature. Likewise, signal injection on induction machines is used on sensorless motor control fields to find out the rotor position. Motor Current Signature Analysis (MCSA), which focuses on the spectral analysis of stator current, is the most widely used method for identifying faults in induction motors. Motor...
متن کاملFault Diagnosis and Fault-Tolerant SVPWM Technique of Six-phase Converter under Open-Switch Fault
In this paper, a new open-switch fault diagnosis method is proposed for the six-phase AC-DC converter based on the difference between the phase current and the corresponding reference using an adaptive threshold. The open-switch faults are detected without any additional equipment and complicated calculations, since the proposed fault detection method is integrated with the controller required ...
