The measuring method for testing lightning protection systems under highly realistic conditions based on various types of the pulse measuring method is noteworthy. Furthermore, a professional earthing analysis can be conducted on the basis of measured interference voltages and interference frequencies. Measurements with various measuring methods:

• Earthing resistance by means of the 3/4-wire measuring method
• Selective earth resistance by means of the 3-wire measuring method with current clamp / advantage: no influence on parallel earth electrodes!
• Earth loop resistance with 2 current claims or Rogowski coils, up to 4 m / advantage: no need to disconnect the earthing system!
• Soil resistivity according to the Wenner method – for the preparation of soil assessments
• Leakage current / current measurement by means of current clamp or flexible current sensor
• Low-resistance measurement with ≥ 200 mA per EN 61557-4 / VDE 0413-4
