Electric Fields of Grounding Electrodes: Frequency and Time Domain Analysis
نویسندگان
چکیده
This paper investigates the influence of frequencydependent electrical soil parameters on underground electric fields associated to the dispersion of lightning currents through grounding electrodes. Results show that the frequency dependence of the soil parameters leads to strong attenuation and distortion of the calculated transient electric fields. It is also shown that both features become more pronounce for less conductive soils and impulsive currents with short front times.

AC Electrophoresis; Deposition of Ceramic Nanaoparticles on In-plane Electrodes at Low Frequencies (RESEARCH NOTE)
Deposition of ceramic nanoparticles (dispersed in a non-aqueous suspension) on in-plane electrodes and under the influence of AC electric fields in the frequency range of 0.01 Hz - 10 kHz is investigated. Analysis of the particle response to the applied field is a difficult task due to the mutual effect of electric- and hydrodynamic force which are present in the system. In this work, however, ...

The paper deals with an assessment of the influence of finite conductivity to the current induced along the horizontal grounding electrode. Analysis is performed in frequency and time domain, respectively. Current distribution along the grounding electrode buried in a lossy half-space is determined via analytical solution of the corresponding Pocklington equation in the frequency domain. The co...

متن کاملA Probabilistic Three-Phase Time Domain Electric Arc Furnace Model based on analytical method
An electric arc furnace (EAF) is known as nonlinear and time variant load that causes power quality (PQ) problems such as, current, voltage and current harmonics, voltage flicker, frequency changes in power system. One of the most important problems to study the EAF behavior is the choice of a suitable model for this load. Hence, in this paper, a probabilistic three-phase model is proposed base...
