In the present era, faults are the greatest interruption for the power system utility. Theses, faults on electrical power systems are unavoidable problems and will continue to happen. These faults are effects on the power system reliability and stability, hence, diagnosis and classification of such faults in rapid and accurate way is an important issue. In this paper, combination method of digi...

Insulated conductors are used widely in overhead power transmission due to the stability and reduced construction space. However, ordinary protection devices not able detect phase-to-ground faults without overcurrent. conductor (IOC) often accompanied by partial discharge (PD) phenomenon. Thus, PD monitoring recognition plays an important role evaluating condition of insulation degradation or d...

abstract introduction: in some individuals because of the poor functioning leg muscles, plantar arch drooping suffered and it seems that ground reaction force individuals with flat foot than to those with normal foot, due to reduced recruitment is altered by the arc. the aim of  the present study the effect of corrective exercise program on the ground reaction force of student with flat food du...

Original scientific paper This paper presents a set of rules for an intelligent algorithm of high impedance fault detection by observing the phase to ground voltage, phase to phase current and harmonics of fault current. Several techniques to detect high impedance faults already exist for example current injection in the neutral, superposing voltage signals, harmonic analysis, neural networks. ...

Abstract High‐resolution interseismic strain mapping is important for studying faulting behavior and assessing seismic hazards. Interferometric Synthetic Aperture Radar has been widely applied to measure deformation along active strike‐slip faults. However, phase unwrapping errors over‐smoothing effects limit its ability map the extremely‐high due shallow creep. Here, without involvement of gro...

The electrical power industry experiences nowadays a significant need in modern techniques for increasing the capability of power transmission systems. The reason for this lies in growing power flows, caused by ris¬ ing power consumption, and in the deregulation of the electrical market, where power flows should be more flexible. These factors demand more transmission capability from the existi...

BERRY, R.F. & BANKS, M.R., 1985 (31 :vii): Striations on minor faults and the structure of the Parmeener Super-group near Hobart, Tasmania. Pap. Proc. R. Soc. Tasm. 119:23-29. ISSN 0080-4071. University of Tasmania, Hobart, Tasmania, Australia, 7000. Fault striations were measured on 104 minor faults within the Parmeener Super-group near Hobart. The fault striations probably reflect the complex...

Large–scale landslides in Valles Marineris wallrock are analyzed in order to determine what triggering mechanisms caused the landslides. These landslides occur in the locality of large faults, and therefore it is hypothesized that the landslides are the result of marsquakes triggering slope instability. This work confirms that landslides occur where the seismic hazard map forecasts highest seis...
