One of the remarkable tectonic features of the Earth’s crust is the widespread presence of long, approximately straight and geomorphically prominent strike-slip faults which are a kinematic consequence of large-scale motion of plates on a sphere (Wilson 1965). Strike-slip faults form in continental and oceanic transform plate boundaries; in intraplate settings as a continental interior response...

Abstract We propose a new definition of oblique plate convergence. Our model considers arc-trench curvature on spherical Earth, and defines obliquity as the angle between direction convergence azimuth from central point along arc to center arcuate trench. also show how this may be extended multiple-arc trenches. apply Western Sunda Arc, which has been traditionally considered prime example conv...

A finite element method with constrained elements and Lagrange multipliers is used to study tectonic faults in a viscous medium. A fault, representing the interface between overriding and subducting plates, has been incorporated into a viscous flow model of a subduction zone in which both thermal buoyancy and the buoyancy associated with the phase change from olivine to spinel are included. The...

DC series arc fault detection is essential for improving the productivity of photovoltaic (PV) stations. The also poses severe fire hazards to solar equipment and surrounding building. faults must be detected early provide reliable safe power delivery while preventing hazards. However, it challenging detect using conventional overcurrent current differential methods because these produce only m...

It is proposed that many summit basins along the Aleutian Arc form from the clockwise rotation of blocks of the arc massif. Summit basins are arc-parallel grabens or half-grabens formed within the arc massif and are commonly located near or along the axis of late Cenozoic volcanism. Geomorphically, the Aleutian Arc appears to consist of contiguous rhombic blocks of varying size, tens to hundred...

The wide variety of arc faults induced by different load types renders residential series fault detection complicated and challenging. Series dc could cause fire accidents adversely affect power systems if not promptly detected. However, in practical systems, they are difficult to detect because a low current, absence zero-crossing period, various abnormal behavior based on loads controllers. I...

This paper presents a location algorithm for series arc fault in low-voltage indoor power line an AC 230 V 50 Hz home network. At both ends of the line, currents and voltages are recorded each generation at different distances. Previously map trace is created by using stored signature coefficients obtained from Kirchhoff equations which allow virtual decoupling line’s mutual capacitance. Then, ...

This paper presents the performance analysis results of a short line fault interruption of a gas circuit breaker, particularly a self-blast type breaker. Hot gas flow analysis was carried out using a CFD calculation combined with the arc model and nozzle ablation. To evaluate the interruption performance, the index function was defined using the pressure in the heating chamber and the density a...
