Earth Ground Testers
Earthing and Grounding system testers for High Voltage and Low Voltage applications
Any mains connected electrical installation will most likely have a grounded electrical system to ensure the safety of the installation and corect operation of protective devices. An Earthing or Grounding System is one or more ground electrodes and conductors which provide a connection between the electrical installation and earth itself. Earth ground testers can be used to measure different characteristics of an earthing system including earth resistance or impedance, interconnection resistances for large earthing systems, earth resistivity tests and much more. Larger earthing systems (for example, substation earth systems) can be fully tested for step, touch and transfer voltages and overall earthing system impedance and performance.
