Influence of LV Neutral Grounding on Global Earthing Systems [PDF]
International Standards define a Global Earthing System as an earthing net created interconnecting local Earthing Systems (generally through the shield of MV cables and/or bare buried conductors). In Italy the Regulatory Authority for Electricity and Gas

Analysis of the Design Calculations for Electrical Earthing Systems
Earthing systems play an essential role in electrical systems in terms of safety for people in the vicinity against the hazard of electric shocks as well as protection and proper operation of equipment during the incidence of faults. Both are achieved by

Plastic contamination of the environment is a global problem whose magnitude justifies the consideration of plastics as emergent geomaterials with chemistries not previously seen in Earth’s history. At the elemental level, plastics are predominantly carbon.

Field Tests: Performances of Practical Earthing Systems Under Lightning Impulses
In this paper, experimental test set and test results on the performance of practical earthing systems under high impulse currents are presented where the earthing systems consist of 3 earthing systems configurations, 2, 3 and 4 rod electrodes ...

Future Generation Computer Systems, 1989
Abstract The ozone hole and greenhouse warming are but examples of changes taking place in our global environment at an unprecedented rate — changes that will have profound implications for our children and grandchildren. They present to the scientists of the world a tremendous challenge: to develop an understanding of the underlying interactions ...
