Optimization of SPIDER Grounded Grid Segment Design
IEEE Transactions on Plasma Science, 2022The ITER Neutral Beam Test Facility (NBTF), built at Consorzio RFX in Padova, Italy, hosts two experimental devices aiming to test and optimize the ITER Heating Neutral Beam Injectors (HNBs) before construction and installation at ITER site. A full size ion source called SPIDER, producing a 5 MW D- or H- ion beam with 100 kV acceleration voltage, is ...

Transient performance of grounding grids
IEEE Transactions on Power Delivery, 1989Understanding the behaviour of grounding systems to transient currents is important to establish the efficacy of protection offered by these systems to personnel and to the electrical installations against lightning. In this paper, an analytical method to determine the transient performance of grounding grids is presented.

Influence of Ground Rods on Grounding Grids
IEEE Transactions on Power Apparatus and Systems, 1979Detailed analysis of ground rods and their influence on horizontal ground conductors, such as those forming grounding grids, is performed assuming a two layer soil stratification. The study starts with a discussion about the adequacy of uniform and two-layer soils as equivalent models for actual soil structures.

Parametric Analysis of Grounding Grids
IEEE Transactions on Power Apparatus and Systems, 1979The results of an extensive study conducted using a computer program designed to determine grounding performance in two-layer soils [1,2,3,5] are described and discussed. A variety of grounding grid configurations and two-layer soil conditions are analysed in detail.

Impulse Impedance of Grounding Grids
IEEE Transactions on Power Apparatus and Systems, 1980A method and an empirical formula to calculate the inductance of square grounding grids fed at either centre or one of the corners is presented. Empirical formulae for the effective area and impulse coefficient for centre fed and corner fel square grids are determinel.

Nonuniform Semi-Infinite Grounded Grids
SIAM Journal on Mathematical Analysis, 1982Semi-infinite resistive grounded grids are countably infinite electrical networks that arise from the discretization of the partial differential equation governing the minority-carrier density in a doped semiconductor. If the doping varies with depth from the surface of the semiconductor, the grid’s resistances also vary with distance from the inputs ...

Resonant grounded grids - quo vadis!?
IET Conference Publications, 2009In earth fault compensated networks the basically capacitive earth fault current is counterbalanced by the injection of an inductive current through the arc suppression coils in such a way, that for most overhead line faults these arcs extinguish without the necessity of disconnecting the faulty grid section.
