Earth Tests

A compliant earth system in high voltage distribution is essential for safe operation.

Gone are the days of merely ensuring the “in service” resistance was less than one ohm!

Electrical Testing Company can carry out:

  • soil resistivity surveys
  • resistance to earth of single or multiple electrode systems
  • measurement of transferred voltages [step and touch potentials]
  • earth potential rise [EPR]

Our test equipment utilises both ac and dc based measurements; and off frequency current injection for verification of computer generated earth system models.
