Research on Hanging Grounding Wire Device with Integrated Electroscope and Grounding

2019 14th IEEE Conference on Industrial Electronics and Applications (ICIEA), 2019
Hanging the grounding wire during the catenary daily power outage operation is the significant link to ensure safe work. While maintaining, the electroscope must be firstly used for electricity inspection before grounding wires. Since the operation is carried out step by step, it is easy to mistake tools and there might be inconsistency between the ...

Lightning Strike at a Grounding Device

Elektrichestvo, 2020
The 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 ...

Testing device for surgical grounding plates

Proceedings of the Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 1992
This 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

Grounding for surge-protective devices ground resistance versus ground impedance

2006 IEEE Power Engineering Society General Meeting, 2006
The 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.

Compact Wireless Devices with Defected-Ground Structures

2006 International Conference on Wireless and Mobile Communications (ICWMC'06), 2006
In this paper are presented some investigations on micro- strip defected ground structures (DGS). It is shown that the presence of a slot in the ground plane can substantially enhance the electric coupling, or the electric part of a mixed coupling between resonators and its external feedings.

Night vision devices for ground environment

IEEE Aerospace and Electronic Systems Magazine, 1999
The PM N-V/RSTA is procuring the Driver's Vision Enhancer (DVE) thermal imaging system for use in combat and tactical wheeled vehicles. The DVE uses uncooled forward looking infrared technology compared to the I/sup 2/ technology currently in the field.
