In designing an effective earthing system, be it for commercial or industrial, the sole aim is to achieve a low earth resistance and doing that doesn’t need to cost you an arm or a foot.

You have to carry out a soil resistivity test among other things.

Once the soil resistivity has been measured from the local soil. The appropriate earth electrode system can be chosen by using typical formulae listed below:

For your earthing system designs, soil resistivity surveys, full earthing analysis and earth resistance measurements, FullSpectrum Energy can help save you the confusion & headaches from Conception, Engineering, Procurement & Supply to Installation and Commissioning.
