Owing to the large magnitude of inrush currents, functionality differential protection power transformer may be threatened in correct discrimination between and internal faults. This article enhances through a computationally efficient method that utilizes phase angle current signals transformers (CTs). The proposed criterion (PDC) tracks fundamental CTs. While during an fault, angles both CTs ...

PV ground faults have caused many fires in the U.S. and around the world. One cause of these fires is a “blind spot” in the ground fault ground fault fuse.. As a result of this discovery, the Solar America Board for Codes and Standards identified a number of alternatives to ground fault fuses, but these technologies have limited historical use in the United States. This paper investigates the e...

background: single leg drop landing is one of the common sport activities that have greater likelihood of leading to traumatic oflower extremity. however, there is limited understanding of biomechanics of this maneuver. hence, this study aimed to compare the activities of lower limb muscles during pre- and post phases of single leg drop landing. methods: this semi-experimental research of 13 ph...

We used scaled experimental (analog) models with wet clay to investigate how conjugate sets of steeply dipping strike-slip faults affect deformation patterns during a subsequent phase of extension. In all twophase experiments, an initial phase of strike-slip deformation produces a long, wide deformation zone consisting of subvertical Riedel shears; synthetic R-shears and antithetic R'-shears tr...
