Earthing modelling of concrete slabs

Utilise Steel Reinforcement in Earthing Designs

Switchgear in substations is installed on top of concrete slabs containing substantial quantities of steel reinforcement. Often the embedded steel reinforcement is bonded to the main earthing system and used to cost-effectively improve earthing electrical performance and safety.

Transmission Line Tower Earthing Analysis using SafeGrid™

Design safe earthing systems for transmission towers

The purpose of transmission line grounding is to provide adequate lightning performance of the line; and effectively dissipate fault current avoiding the build-up of unsafe step and touch potentials around the tower base.

Extensive Study of Earthing Grids

Parametric study of earthing system performance.

An extensive study of earthing grids using SafeGrid software designed for determining performance of grids of arbitrary geometrical configuration in two layer soils has been undertaken. The study confirms work by Dawalibi and Mukhedkar undertaken using similar software called CDEGS®.

Comparison of substation safety criteria given by the American (IEEE) and European (IEC) Standards

Calculate touch and step voltage limits to different Standards and understand the differences

This report will focus on safety hazards caused during fault conditions.

Use of Rods to Improve Grid Safety

Use vertical rods to reduce grid resistance and voltages to improve the safety of earthing systems

To show how and when earthing rods can be used to improve the safety of earthing grids by reducing the grid resistance and potential rise (GPR) as well as surface, step and touch potentials.

How to model conductors surrounded by additional substance using SafeGrid

Model the effects of Bentonite, Marconite or equivalent enhancement materials surrounding buried earthing conductors.

To model the influence of an additional substance surrounding the conductors of a buried earthing system on grid resistance, touch and step voltages.
