Application Modeling of Substation Grounding Grid Design Using Matlab
2022 6th International Conference on Electrical, Telecommunication and Computer Engineering (ELTICOM), 2022The grounding system is an important element in the electric power system as one of the protections to protect equipment damage due to fault currents. In determining the calculation of the substation grid design, software is used to simplify calculations

Transient performance of grounding grids
IEEE Transactions on Power Delivery, 1989Understanding the behaviour of grounding systems to transient currents is important to establish the efficacy of protection offered by these systems to personnel and to the electrical installations against lightning. In this paper, an analytical method to determine the transient performance of grounding grids is presented.

Influence of Ground Rods on Grounding Grids
IEEE Transactions on Power Apparatus and Systems, 1979Detailed analysis of ground rods and their influence on horizontal ground conductors, such as those forming grounding grids, is performed assuming a two layer soil stratification. The study starts with a discussion about the adequacy of uniform and two-layer soils as equivalent models for actual soil structures.

Parametric Analysis of Grounding Grids
IEEE Transactions on Power Apparatus and Systems, 1979The results of an extensive study conducted using a computer program designed to determine grounding performance in two-layer soils [1,2,3,5] are described and discussed. A variety of grounding grid configurations and two-layer soil conditions are analysed in detail.
