Este trabalho tem como objetivo analisar o desempenho de uma malha de aterramento de acordo com sua resistência. O aterramento está atrelado a dois fatores fundamentais: o desempenho do sistema ao qual o aterramento está ...

This dissertation studies a new technique for measuring the transient response of grounding systems, notably impulsive impedance, using an arrangement of special conductors in the current circuit. Such conductors, called ...

This PhD thesis presents a technique used in grounding impedance and resistance measurementswhere the current circuit consisting of a typically long single wire is replaced by an Artificial InfiniteLine. Due to the ...

The reliability and availability of the electric power transmission system is severely influenced by lightning. In Brazil, roughly 65% of the overhead transmission lines outages are due to lightning, whereas the backflashover ...

The unplanned outages that occur on a transmission line is one important parameter in defining their performance, being the lightning the main event responsible for such occurrences. A technique widely used as a preventive ...

This research presents the necessary points to carry out a substation grounding project, focusing on the theoretical part and mainly on the safety of the workers and electronic equipment installed in these locations. ...
