Arc fault is one of the primary reasons that cause electrical fire. When arc fault occurs in power supply line, the current can not make protective equipments act and the arc fault can not be found and cut off easily, so electrical fire comes into being. In the comparisons, the current signal is used for the detection physical parameter and the wavelet transform is used to study the arc fault d...

Cho A clonal selection programming (CSP)-based fault detection system is developed for performing induction machine fault detection and analysis. Four feature vectors are extracted from power spectra of machine vibration signals. The extracted fea...

It is well known that series arc faults in Low Voltage DC (LVDC) distribution system occur at unintended points of discontinuity within an electrical circuit. These faults can make circuit breakers not respond timely due to low fault current. It, therefore, is needed to detect the series fault for protecting circuits from electrical fires. This paper proposes a novel scheme to detect the series...

As the fault information of power transformers has characteristics such as complementarities, redundancy and uncertainty, the diagnosis task can’t be finished by the simple fault characteristic vector and the diagnosis method. The basic ideas of information fusion are introduced, and DGA (the Dissolved Gas Analysis) is combined tightly with other information such as the results of conventional ...

Photovoltaic (PV) systems have caused residential and commercial building fires when an electrical arc fault initiates in the conduction path. Article 690.11 in the United States 2011 National Electrical Code requires new photovoltaic systems on or penetrating a building to include a listed arc fault protection device to prevent additional fires. In response, manufacturers are creating arc faul...

Received Jan 29, 2017 Revised Mar 29, 2017 Accepted Apr 10, 2017 Recently, research has picked up a fervent pace in the area of fault diagnosis of electrical vehicle. Like failures of a position sensor, a voltage sensor, and current sensors. Three-phase induction motors are the “workhorses” of industry and are the most widely used electrical machines. This paper presents a scheme for Fault Dete...

The main objective of this paper to detect an arc fault occurring in a low voltage dc system using wavelet transform. As we know arc faults plays a major role in an electrical power system, due to this fire, shocking hazard or system failure of the electrical system or equipment can be happen. It’s very challenging to detect arc fault in a dc system because unlike a ac system a dc system cannot...

An important part of developing an effective building code is the adherence to strict safety codes. Electrical safety and the associated issue of fault current breaker performance, in particular, are extremely important in this regard since the nature of electricity consumption in the Kingdom of Saudi Arabia and the improved style of living have led to a continual increase in the consumption de...

A vital attribute of electrical power network is the continuity of service with a high level of reliability. This motivated many researchers to investigate power systems in an effort to improve reliability by focusing on fault detection, classification and localization. In this paper, a new protective relaying framework to detect, classify and localize faults in an electrical power transmission...
