This work presents a technique for electrical grounding system representation, directly in the time domain. It is based on the theory of least squares and starts from harmonic grounding impedance, representing it by discrete ...

Grounding systems are essential to dissipate fault currents into soil to guarantee safe conditions to personnel and equipment. In this context, several approaches have been employed to calculate tower-footing grounding ...

A one-port nonlinear electric circuit to simulate grounding systems behaviors under high impulse currents is presented. The circuit is based on Loboda's and Pochanke's equations, which describe nonlinear behaviors of soil ...

This paper proposes a dedicated algorithm for lation of single line-to-ground faults in distribution systems. The proposed algorithm uses voltage and current phasors measured at the substation level, voltage magnitudes ...

In this work we characterize the electromagnetic response of archaeological remains of a Spanish fortress situated onthe Atlantic coast in Patagonia (Argentina). The fortress, part of the Floridablanca colony, founded in ...

Electrical grounding systems have the function of protecting electrical installations and equipments, as well as the person's life who may be in contact with it. Reducing ground resistance is one of the principal factors ...

Grounding electrodes are essential in electrical power system to maintain a reliable operation, and to guarantee the safety of personnel and equipment. When a lightning strikes at a transmission tower, surge current waves ...
