Earthing of Electrical Systems

Parallel Computing Aided Design of Earthing Systems for Electrical Substations in Non-Homogeneous Soil Models

An accurate design of grounding systems is essential to assure the safety of the persons, to protect the equipment and to avoid interruptions in the power supply. In order to attain these targets, it is necessary to compute the equivalent electrical resistance of the system and the potential distribution on the earth surface in fault conditions. In this paper, a numerical approach for grounding...

The neuromodulative role of earthing.

Neuromodulation is a process of inhibition, stimulation, modification and regulation or therapeutic alteration of activity, electrically and chemically in the peripheral, central or autonomic nervous systems. Direct electric current or electric field alternates the function of nervous system. Coupling the human organism with the Earth directly or via a wire conductor changes the electric potent...

HV Substation Earthing Design for Mines

-High Voltage (HV) substation forms important assets for the mining industries. The existences of these substations necessitate earthing design to ensure safety compliance to the mine regulations. The HV system within the mines is consisted of multiple substations which are connected throughout and underground cable. These substations provide the load with the required electrical power to perfo...
