Earth Testing Services

The best protection systems in the world become unstable when the earthing of the network doesn’t meet the design criteria. The design and installations require expert commissioning with specialised equipment, by qualified technicians. Ongoing monitoring of the earth grid network is required for the life of the network, to maintain the functional integrity to highest standards.
GTS has the capability to help with all aspects of this, literally from the ground up.


One of the objectives of a good earthing system is to provide the means to carry electric current into the earth under normal and fault conditions without exceeding operational or equipment limit or adversely affecting continuity of service.

A good earthing system should also ensure that a person in the vicinity of earthed equipment or facilities is not exposed to the danger of electric shock. At GTS, we have the personnel, the test equipment and the software resources to test and validate any earthing system, at any voltage level. Whether it is a statutory requirement, maintenance program work, or for the safety of personnel, GTS has the capability to conduct the following earthing testing services:

  • Step & Touch Potentials
  • Earth Potential Rise (EPR)
  • Field Soil Resistivity Testing using Wenner Four –Electrodes Method
  • Soil Resistivity Modelling
  • Earth Continuity Test
  • Off Frequency Current Injection Test
  • Current Distribution Test
  • Fall of Potential Contours Test
  • Earth Grid Testing
All our earthing system test procedures are compliant to Standards such as; IEEE Std 80:2000, IEEE Std 81:2012, AS2067:2008, AS/NZS 3835.2:2006, and all relevant statutory requirement.
