Globality levels of grounding systems

open access: yes2014 IEEE/IAS 50th Industrial & Commercial Power Systems Technical Conference, 2014
IEC Standard 61936-1 “Power installations exceeding 1 kV a.c.” defines the “Global Grounding System” (GGS). It consists essentially in the interconnection of the MV/LV grounding systems, generally at least by means of the MV cables metal sheaths and/or of dedicated ground conductors buried along the MV cable lines.

Common grounding system

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

Intrinsically Safe Grounding Systems and Global Grounding Systems

IEEE Transactions on Industry Applications, 2018
This 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.

Power Grounding Safety: Copper Grounding Systems vs. Steel Grounding Systems

2006 International Conference on Power System Technology, 2006
More 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.
