Observes a small difference, however, between the full and simplified hydrodynamic models. © MCB UP Limited 1996 Electrical engineering Electricity Methods...

... as a flexible tool for determining the field distribution of electrical systems. In many applications the method is used as an intermediate step for the evaluation of design quantities such as capacitance, conductance and inductance, by post‐processing of the determined potential distribution. In many respects...

...G. Aiello; S. Alfonzetti; S. Coco; N. Salerno Charge iteration is an iterative procedure for the finite element computation of unbounded electrical fields, created by voltaged conductors. It makes use of a fictitious boundary, enclosing all the conductors, on which the electrical potential is first...

...G. Chen; A.E. Davies The electric stress profiles of a needle‐plane electrode system used in the laboratory for investigation of tree initiation and growth have been studied. Results from analytical solution based on a hyperboloid shaped needle tend to differ from those from experiments. One reason...

... barrier, serves as a return path for fault currents and is an outer screen for the electric field. Whereas the conductor is usually copper or aluminium, owing to costs the sheath is made from aluminium, lead or steel (in the case of gas insulated systems). The sheath material must be able to carry fault...
