The C.A 6470N offers approximately 10 times greater accuracy thanks to its four-pole earth measurements. This method allows measurements of low earth resistance values, which are essential to meet the requirements of power distribution and transmission companies (EDF and RTE in France)
Tester for all types of earth measurements, including pylon earth measurements (with the C.A 6474) – soil resistivity – earth coupling – ground potential – continuity & resistance
The C.A 6472 can be used for quick, comprehensive surveys of all earthing configurations, offering all the necessary earth measurement functions in a single instrument.
When used with the C.A 6474, it can also perform pylon earth measurements, making it a unique but essential tool for diagnostics and maintenance on pylon networks.
The C.A 6472 offers the possibility of analysing the frequency behaviour of the earth connections thanks to its extensive measurement frequency range (41 to 5,078 Hz). The use of a high-frequency measurement signal makes it possible to assess the behaviour of an earthing circuit in the presence of lightning.
