In the last years the authors have developed a numerical formulation based on the Boundary Element Method for the analysis of grounding systems embedded in uniform soils. This approach has been implemented in a CAD system that currently allows to analyze real grounding grids in real-time in personal computers. The extension of this approach for the grounding analysis in layered soils is straigh...

The purpose of this research is to look at the reason significant zero sequence transients in ac lines caused by a surrounding earth return dc circuit. A qualitative reasoning as well quantitative parametric examination are offered. results reveal that even for relatively close lines, very can occur. Furthermore, appear only when non-zero ground resistivity incorporated model. Different resisti...

This article presents a new method for locating faults along feeders in direct current (dc) microgrid using multiple capacitive earthing scheme. During fault conditions, capacitors within the scheme are charging by transient currents that correlate with distance and resistance. Therefore, assessing response of during fault, to is estimated. The proposed utilizes instantaneous voltage measuremen...

For protection against electric shock in electrical equipment, particularly control or instrument installations substation a quality earthing system is required. The also affected by soil resistivity with different types. In the equipment grounding system, knowledge of types electrodes and type At Prabumulih substation, Podzolic required to evaluate stress distribution that happens order reduce...
