[Resumen] En esta tesis doctoral se presenta una formulación numérica general para el cálculo y el diseño asistido por ordenador de tomas de tierra en instalaciones eléctricas. En primer lugar, se identifica la naturaleza ...

[Resument] A model for the propagation of water waves is presented, which retrieves the concepts of rays and fronts from the geometrical optics approximation. Their definition here is nevertheless different in that it ...

[Resumen] La puesta a tierra de una instalación eléctrica es imprescindible para garantizar su seguridad cuando tienen lugar situaciones de fallo. Para su correcto diseño se requiere la determinación de una serie de ...

[Abstract] Grounding systems are designed to preserve human safety and grant the integrity of equipments under fault conditions. To achieve these goals, the equivalent electrical resistance of the system must be low ...

[Abstract] Substation grounding design involves computing the equivalent resistance of the earthing system -for reasons of equipment protection-, as well as distribution of potentials on the earth surface -for reasons of ...

[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 ...

[Resumen] La modelización de problemas en mecánica de fluidos cuando la velocidad del fluido es elevada resulta complicada debido a la aparición de inestabilidades en la solución numérica al emplear esquemas convencionales ...

[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 ...

[Abstract] Analysis and design of substation earthing involves computing the equivalent resistance of grounding systems, but also distribution of potentials on the earth surface due to fault currents [1]. While very crude ...

[Abstract] Several widespread intuitive techniques developed during the last two decades for substation grounding analysis, such as the Average Potential Method (APM), have been recently identified as particular cases of ...
