Designing an effective grounding system for AC substations needs predetermination of
ground resistance and ground potential distribution caused by fault current's presence in the …

The purpose of designing suitable grounding system is to ensure reliable power supply,
safety of equipment and people working in electrical power operation and to limit voltage …

In this paper, comparative assessments of four earthing grid system configurations (the
triangular shape, the rectangular shape, the T-shape and the L-shape) are performed with …

In addition to the soil resistivity and size of the grounding system, grounding system
configuration can influence the steady-state resistance (RDC) of a grounding system. The …

Current practice for grounding system design is mainly guided by IEEE 80-2000 standard.
This practice is an iterative process of changing design variables until safety requirements …

To meet the high demands on the electrical power due to the growth in populations more
high voltage projects are captured by the development scopes. To save on easement cost …

Soil layer resistivity modelling is a vital component of grounding system design. Grounding
system for facility, equipment, power station and general system protection purposes must …

This paper presents empirical formulas which can be used for designing the grounding
system in two layer soil model for both Gas Insulated Substation (GIS) and Air Insulted …

Earth mat provides a common ground for the electrical equipment as well all the metallic
structures in the substation. The personnel safety and protection of equipment depends …

In a substation, several equipment require connection to the earth at various locations to
maintain equipotential platform, hence the need to provide very low resistance path for fault …
