Overvoltage Analysis of Transmission Towers Considering the Influence of Tower-Footing Impedance
(Ieee, 2017-01-01)
Lightning is one of the main causes of outages due to backflashover mechanism in power systems. In this context, the tower-footing impedance presents a key role in the overvoltages caused by this phenomenon. Tower-footing ...

A dependência entre a condutividade hidráulica saturada e atributos físicos do solo
(Universidade Federal de Santa Maria, 2004-06-01)
The saturated hydraulic conductivity of the soil (Ksat) is one of the most relevant variables for studies concerning water and solutes movement in soil. Its determination in laboratory and field gives results with high ...
Investigação da resposta de malhas de aterramentos frente a correntes de descargas atmosféricas
(Universidade Federal de Minas GeraisUFMG, 2013-07-24)
The response of grounding grids subjected to lightning currents wasassessed following two different approaches: experimental tests andcomputational simulations. The experimental tests comprise the impression of currents ...
