For large earthing systems the heavy-current method is used in order to measure the potential rise as well as touch voltages at frequencies close to the power frequency.

  • Measurements of earth potential rise of large systems
  • Measurements of touch and step voltages
  • Measurements of earth resistance of small and medium electrode systems
  • Calculations of power frequency and transient behavior
  • Training of personnel in electric utilities and consultants
