Chauvin Arnoux Earth Resistance Kit
The Chauvin Arnoux CA 6474 vectorial processing unit combined with the Chauvin Arnoux CA 6472 Earth Resistivity Tester can be used to measure the earth resistance of a pylon, even if it is part of a parallel earthing network, by selective measurement of the pylon under test. A single measurement can display readings of overall impedance of the line, earth resistance of the pylon considered, resistance of each pylon footing and quality of the protective earth cable
The C.A. 6474/6472 Pylon Earth Test Kit, combining the C.A. 6474 adapter with the C.A. 6472 earth tester, offers a comprehensive solution for pylon earth resistance measurements. This kit enables engineers to perform critical assessments without the need to disconnect overhead earth cables, enhancing both safety and efficiency. Utilizing four flexible current sensors (AmpFlex) positioned around the pylon's footings, the system conducts frequency scans up to 5 kHz, allowing precise measurement of earth impedance. This capability is vital for analysing the frequency behaviour of earthing systems, particularly in response to lightning strikes. The kit's wide measurement range and high resolution ensure accurate results, while its ability to reject interference voltages up to 60 V peak enhances reliability. Designed with user convenience in mind, the system automatically calculates earth coupling coefficients and ground resistivity using the Wenner or Schlumberger methods upon input of rod distances. Its robust construction, featuring IP53 protection, makes it suitable for field use in various environmental conditions.
