The selection of power distribution components is great importance in electrical facilities. Cable and busbar systems are widely used applications, such as electric vehicle charge stations, microgrids energy storage systems, for the grid. In this study, current on parallel conductors magnetic field distributions around cable structures evaluated studied application where distributed using a sys...

The calculation of the load carrying capacity of variable thickness circular plates subjected to arbitrary rotational symmetric loading is presented. The analysis considers plate materials that obey either the square or the Tresca yield criterion. By using upper and lower bound theorems of limit analysis, corresponding estimations for the load carrying capacity of the plate are obtained. It is ...

Abstract When the ±800kV UHVDC capacity is increased to 10000MW, transmission current 5kA and 6.25kA, which will put forward new requirements for key technology of through wall bushing: in UHV level, bushing lies research basic voltage sharing field sharing. In case large carrying capacity, heat DC bushing, converter outgoing line device operate at rated voltage, central conductor heated due cu...

abstract to resist lateral loads in concrete buildings, usually systems such as flexural frame, shear wall or their combinations are used. using x form of cable bracing in order to strengthen concrete buildings is a new method. this system is more economical compared with the other systems due to cables low weight, high tensile resistance, easy performance and less maintenance problems. in this...

The relation between the fine structure, electric field equations, and electric circuit models of skeletal muscle fibers is discussed. Experimental evidence illustrates the profound variation of potential with circumferential position, even at low frequencies (100 Hz). Since one-dimensional cable theory cannot account for such variation, three-dimensional cable theory must be used. Several circ...

Calculate the electromagnetic momentum and identify the “hidden” mechanical momentum in a coaxial cable of length L, inner radius a, outer radius b, when a battery of voltage V is connected to one end and a load resistor R0 is connected to the other. The current may be taken as uniformly distributed over the inner conductor, which has resistivity ρ. The outer conductor has negligible resistivit...

The equation for an equivalent LRC-circuit of current-carrying magnetic loop is obtained. It is suggested that the electric current, driven by the converging flows in the photosphere, flows trough the coronal part of a loop from one footpoint to another, and closes deep in the photosphere where plasma beta β ≈ 1. In a self-consistent approach both the capacitance and the resistance of a LRC-cir...

First I emphasize the magnetospheric loop current system induced by the wind activity. Next, I address the formation of the fieldaligned electric field. An interesting aspect is the reaction of the inner magnetosphere to an induced current. In the traditional outer gap, the current running through the gap is all carried by the particles created in the gap. However, if external current-carrying ...
