In this paper, we compare five engineering return stroke models, extended to include the presence of an elevated strike object, namely the Bruce-Golde (BG) model, the transmission line (TL) model, the traveling current source (TCS) model, and the two modif ...
The study of the interaction of lightning electromagnetic fields with electrical systems and the design of appropriate protection strategies are generally based on statistical distributions of the lightning current measured at the channel base using either ...
Current from nearby rocket-triggered lightning that flowed through the soil and into an unenergized test power distribution line was studied based on experimental data acquired in 2003 at the International Center for Lightning Research and Testing in Flori ...
The peak current estimation of lightning detection networks for strikes to tall towers is discussed in this paper. Such systems are sometimes calibrated using return-stroke current data obtained by means of rocket-triggered lightning or instrumented towers ...
This review paper, prepared for this second special issue on lightning of the IEEE TRANSACTIONS ON ELECTROMAGNETIC COMPATIBILITY, summarizes major publications on lightning and lightning protection since the first special issue published in November 1998, ...
The power system has been used for communication purposes for many decades, although it was mainly the power utility companies that used low bit rates for control and monitoring purposes. In the last ten years, however, the deregulation of the power and te ...
The aim of this paper is to present the results of the performance study of medium voltage overhead distribution lines against lightning discharges, in the way to define methodologies to reduce the system failures. The results are obtained within the partn ...
One of the characteristic features of the electromagnetic fields radiated by lightning is the far-field inversion of polarity with a zero-crossing occurring in the tens of microseconds range. This feature has been used in several studies to test the abilit ...
This paper deals with the calculation of lightning-induced overvoltages on medium-voltage (MV) and low-voltage (LV) distribution networks taking into account the presence of MV-LV distribution transformers and, in particular, the surge transfer through the ...
Monitoring units for the measurement of high frequencyvoltage transients have been in operation at three different busses of an Italian medium voltage (MV) distribution feeder, mainly composed by overhead lines, in March 2007 – August 2008. The feeder is l ...
