Unified Grounding Systems for Future Projects to Ensure Public Safety and Improve Performance

This study provides a comprehensive analysis of earthing systems as defined by international standards. It involves the calculation of fault currents and contact voltages, the selection of suitable electrical protection for each system type, and an evaluation of the currently implemented systems. The research highlights the distinctions in system performance, focusing on supply continuity and the corresponding protection mechanisms. It also addresses methods for defining neutral points in both high and low voltage networks. Furthermore, the study examines the effectiveness of protective devices during ground faults, including the implications of unearthed neutral systems. Both existing and proposed methods of…
