A meshless numerical approach for the analysis of earthing systems in electrical installations
(Technische Universität München, 1999)
[Abstract] In the last three decades some numerical formulations have been developed for solving potential problems in electrical engineering applications. In the particular case of the grounding analysis area, in recent ...
A boundary element numerical approach for earthing grid computation
(Elsevier, 1999)
[Abstract] Analysis and design of substation earthing involves computing the equivalent resistance of grounding systems, as well as distribution of potentials on the earth
surface due to fault currents [1,2]. While very ...

A stabilized finite element approach for advective-diffusive transport problems
(Escola Politécnica da Universidade de Sao Paulo, 1999)
[Abstract] As it is well-know, the numerical simulation in fluid mechanics is quite difficult specially when the velocity of the fluid is important. These problems are reflected in the apparearance of numerical oscillations ...
Development of a CAD system based on a BEM approach for earthing grids in stratified soils
(Elsevier, 1999)
[Abstract] The design of safe earthing systems is esential to assure the security of the persons as well as the protection of the equipment and the continuity of the power supply. For the attainment of these aims, it is ...
