A Direct Current Circuit Breaker (DCCB) is an electrical device designed to protect DC circuits from overcurrents and short circuits, ensuring safety and reliable operation. Unlike traditional AC ...

ABSTRACT: The purpose of this study was twofold: first to investigate the effect of conceptual change oriented instruction accompanied by concept cartoon worksheet with simulation on students’ ...

THE second edition of this text-book is a creditable effort on the part of the author to cover, in a single volume of 730 pages, the extensive field embracing the theory and applications of direct and ...

Abstract: Direct current circuit breakers (DCCBs) are characterized by their fast response and limited fault propagation, making them widely applicable in the protection of modular multilevel ...

Abstract: The high voltage direct current (HVDC) transmission lines represent the prospective way for long-distance transmission between countries, remote areas, and offshore wind farms to decrease ...

IN a paper read before the Institution of Electrical Engineers on March 6, D. C. Gall describes the design and behaviour of a direct-current amplifier, entirely alternating-current mains-operated, and ...
