The detection of series arc faults using fault current is difficult to overcome the influence load types, making it establish a unified criterion. In contrast, since voltage waveform point less affected by types and basically square wave shape, which provide conditions for constructing terms information, distortion on load-side caused transition edge provides position information edge, its pola...

Accurate faulty phase detection under single-line-to-ground (SLG) fault is the basis of emerging voltage-based arc suppression technology. Most conventional recognition criteria assume distributed line-to-ground parameters are symmetrical, therefore suffering invalidity in actual distribution networks especially high-resistance ground-fault conditions. This paper firstly analyzes magnitude and ...

The El Salvador Fault Zone (ESFZ) is part of the Central American Volcanic Arc and accommodates oblique separation movement between forearc sliver Chortis block (Caribbean Plate). In this work, a triclinic transtension model was applied to geological (fault-slip inversion, shape volcanic calderas), seismic (focal mechanisms) geodetic (GPS displacements) data evaluate characteristics last stages...

• 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 ...

The Lut Block (Eastern Iran) extends over 900 km in a north-south direction and is only 200 km wide in an east-west direction. It is confined by the Nayband fault and Shotori Range on the west. The eastern edge is bordered by the Sistan suture zone and Nehbandan Fault. The northern termination of Lut Block is the depression of Kavir-e-Namak and the Great Kavir Fault. The Makran arc, including ...

Low-voltage arc quench is one of the most processes for a successful power interruption in circuit breakers. Typical breakers are designed to switch off fault current within half cycle, less than 10 milliseconds, which requires an efficient and thus poses great challenges interruption. Apart from using electronics, very expensive low capacity, classical that uses stack steel plates split fault-...

A long-gap ac arc with a length of more than 10 m (secondary arc) is normally generated at the short-circuit channel after single-phase-to-ground fault. In previous studies, breakdowns secondary arcs have mainly been considered as electrical breakdowns, ignoring role heat in channel. Besides, extinction-reignition theory arc, i.e., dielectric strength recovery theory, still lacks support experi...

the nayband strike-slip fault forms the western margin of the micro-continental lut block in eastern iran. neogene and quaternary mafic volcanic rocks collected near tabas, along the northern part of the fault (nnf; 15 ma), and further to the south, along the middle part of the fault (mnf; 2 ma), are within-plate sodic-series alkali olivine basalts with high tio2 and up to >16% normative nephel...
