IEEE Systems Technical Conference on Industrial and Commercial Power 2005., 2005
Current European Standards (HD 631 S1-1999 E) have fostered the so-called "common grounding system" (CGS) concept. It consists in the interconnection of the grounding systems of all the MV/LV substations of a MV network together to the HV/MV substation grounding grid, by means of the MV cables' metal sheaths and/or of dedicated ground conductors buried

Power Grounding Safety: Copper Grounding Systems vs. Steel Grounding Systems
2006 International Conference on Power System Technology, 2006More and more conventional grounding systems made of steel are being replaced with copper grounding systems in Asian countries. This paper analyzes the performance of grounding systems made of steel or copper conductors, taking into account the impedances of the ground conductors.

Intrinsically Safe Grounding Systems and Global Grounding Systems
IEEE Transactions on Industry Applications, 2018This paper introduces a characterization of grounding systems (GSs) and defines their condition of “conventionally safe” and “intrinsically safe.” A single GS and a set of GSs are intrinsically safe if they guarantee touch/step voltages permanently permissible for an assigned ground fault value.

SpaceOps 2012 Conference, 2012
Ground systems have a very specific function, defined at design phase, and are not used for anything else. Hence, the processes, libraries, files, network connections and other resources used are clearly specified and stable unless an approved change takes place.

1990
The purpose of this study was to document construction procedures, monitor field performance, and make recommendations as to the effectiveness and future use of stone column and wick drains for ground modification purposes. This project involved the use of wick drains to accelerate consolidation in bridge approach foundations and stone columns to ...

Ground Penetrating Radar System: Principles
2022Ground penetrating radar is a geophysical survey method widely applied to the assessment and monitoring of cultural heritage buildings. It is commonly used as a method of structural evaluation because it is nondestructive and noninvasive. This chapter describes the historical development of the method and explores the fundamentals and theory of ground ...

SOHO operations and ground system
Space Science Reviews, 1994SORO is a joint ESA/NASA mission to study the sun from its interior to, and including, the solar wind in interplanetary space. It is currently scheduled for launch in 1995. After launch SORO will be operated from the Experiment Operations Facility (EOF) at Goddard Space Flight Center (GSFC). The EOF will consist of facilities for instrument commanding,

GROUND CONDUCTOR FOR A GROUNDING SYSTEM
2001A ground conductor for grounding systems of electrostatic separators, comprising an electroconductive core with a plastic or rubber sheath. In order to prevent the liquids from flowing therethrough, the inventive ground conductor consists of two conducting parts, the conducting parts are joined to each other by means of a liquid-tight graphite part ...
