Intention

The LPI Earthing Calculator is designed to give an indicative result to assist with the preliminary planning of an earthing installation. It calculates both the expected system resistance, and the quantity of Grip or Reslo earth enhancing compounds. All calculation use formulas taken directly from recognised IEEE and AS1768 standards.

Limitations

The LPI Earthing Calculator is provided as is and LPI does not warrant or accept responsibility for the results provided.
Whilst the formulas used cover a range of common simple arrangements, the design of an earth system (including the input parameters) requires engineering judgement and all results should be verified by an appropriately qualified engineer taking into account such things as step and touch potential, site layout, materials, fault current, and so on.
If in doubt, contact the below to make use of LPI's design service: design@lpi.com.au
