Lightning Strike at a Grounding Device
Elektrichestvo, 2020The statistical distributions of lightning current parameters obtained from an analysis of natural lightning waveforms carried out by three research centers are considered, and it has been found from the consideration results that the extreme values of these parameters, based on which the recommendations of the relevant IEC standards were elaborated ...

Modelling of transmission tower considering the surge response of tower grounding device
Workshop on Automated Control for Datacenters and Clouds, 2020Surge propagation on transmission tower is a concerning issue in lightning protection, particularly in predicting overvoltage on electrical power system as well as providing reference information for surge protection design. Transmission towers have been

Grounding for surge-protective devices ground resistance versus ground impedance
2006 IEEE Power Engineering Society General Meeting, 2006The aim of this paper is to address the often loosely used terms of impedance and resistance as related to grounding, and to educate the reader as to the significant difference between these two terms when contemplating the behavior of grounding systems impressed with transient impulse currents.

Testing device for surgical grounding plates
Proceedings of the Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 1992This paper reports about a new device for safety test of disposable grounding plates for electrosurgery. Neutral electrodes (grounding plates, dispersive electrodes) must fulfill the requirements of the american AAMI HF-18 standard. Instead of measurements on human volunteers an electronic devive was built to simulate human skin. Its conductive surface
