The Impact of Substation Grounding Grid Design Parameters in Non-Homogenous Soil to the Grid Safety Threshold Parameters

It is important to ensure that a grounding system designed with low magnitude of earth resistance, so the protection can divert large fault current effectively. The performances and level need be acknowledged as condition soil structure changes different characteristics. At present, there lack systematic guide or standards for grid designs consider non-uniform its impact on systems. By computing safety threshold parameters consisting impedance, step, touch voltages, comparison has been made between uniform two-layer models. Where competence systems depend attributes, significant various conditions seen. evaluations performance assessment in hold novelty originality no such discussion have date. These comparisons would help forecasting behavior environments, which provide engineers additional expertise design an effective secure system. This research contribute existing body knowledge by differentiating predicting when characteristics differ significantly from most guidelines only while designing system, owing complexity at site.
