• On-site soil resistivity testing as inputs to the calculations and modelling,

• Creation of an earth-grid model using CAD services.

This model is then used within CDEGS ^(R) software to asses:

• Touch and step voltages around the site and adjacent areas,

• Earth grid impedance, EGVR and EPR,

• Impact on adjacent services (e.g., telecommunications, other earth grids, MEN system, water pipes etc).
