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 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 ...

This thesis presents the development of an automated scanner for measuring sequential impulsive responses, to be applied on the spatio-temporal characterization of materials, used in acoustic treatment. The system uses ...

This work presents the results of an experimental investigation about the behavior of grounding electrodes subjected to low intensity impulsive currents, whose waveforms are similar to the lightning ones. Basically the ...

This Ph.D dissertation presents a new grounding impedance measuring system, based on DSP (Digital Signal Processor) platform. The low-cost portable device includes a built-in voltage impulse generator, non-volatile memory ...

A set of concepts capable of defining a new perspective for grounding arrangements characterization is developed. It is based on three distinct and totally innovative measurement proposed methods. Initially, a survey of ...
