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!
Our Services
- 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.
