The C.A 6472 earth and resistivity tester can be used for quick, comprehensive testing of all earthing systems by gathering all the earth measurement functions in a single instrument. When used with the C.A 6474, it also offers pylon earth measurements, making it an essential tool for diagnosing and maintaining the earthing systems of all types of pylons. Unlike traditional earth testers, the C.A 6472 offers the possibility of analysing the frequency behaviour of earthing systems thanks to its particularly extensive measurement frequency range (from 41 to 5,078 Hz). The use of a high-frequency...

GROUND RESISTIVITY MEASUREMENT Wenner method: the distances between the 4 rods are identical: d ρW = 2.π.d.RS-SE Schlumberger method: the distance between the 2 central rods S & ES is A the distance between the 2 outside rods E & H is 2d ρS = (π.(d2-A2/4).RS-SE) /4 When it is possible to choose the position of the earth connection, resistivity measurement helps to assess the ground and thus determine the place where the earth resistance will be lowest (optimization of construction costs). The C.A 6472 automatically calculates the resistivity of the ground (ρ) using the Wenner or Schlumberger...
