Chauvin Arnoux CA6417 Earth Clamp Meter
With it’s 600V CAT IV rating, 35mm jaws and dangerous voltage alarm, the Chauvin Arnoux CA6417 Earth Clamp meter is ideal for quick earth-loop resistance measurements in parallel ground networks. Ideal for large conductors and in applications where the access to conductors is restricted.
Capable of simultaneously displaying impedance and leakage current, earth voltage and a breakdown of ground impedance, the CA6417 Earth Clamp offers a range of useful functions, including automatic jaw calibration to ensure accuracy, a HOLD button and automatic PRE-HOLD when the clamp opened.
With a rotary dial switch for selecting tests and an ergonomic design, the CA6417 is incredibly easy to use, featuring a protective guard, a force compensation system for easy clamp opening and an OLED display for visibility over 180° regardless of lighting conditions.
Coming complete with a carrying case to keep the instrument secure, the Chauvin Arnoux CA6417 Earth Clamp also features Bluetooth communication, the ability to interface with GTC, DataView PC software and/or the ANDROID app.

Ground measurements in urban areas are often difficult because it is not possible to set up ground stakes. The CA6417 ground clamp meter can be used to perform selective measurements on a parallel ground system without disconnecting conductors or even setting up stakes.
In the case of regularly-spaced ground connections or an underground ground loop, the use of ground clamps to measure low values allows you to check the continuity of the loop conductor tested.
Measurement of grounds in parallel on MV/LV installations: To ensure the quality of the ground present on the whole distribution network, an extended ground is set up using all the local grounds in parallel: grounds of electricity poles, building grounds, etc.
Ground measurements in urban areas and/or on buildings with Faraday cages: On buildings in urban areas where the grounding system comprises numerous ground connections in parallel and in buildings equipped with sensitive electronic equipment, a network of ground conductors connected to multiple grounds helps to equalize the potential of the chassis-grounds, particularly in the event of storms.
Measurements on telecommunications lines: To protect their line from disturbances, the telecommunications line provider isolates the cable by means of a conducting sheath connected to the ground over its whole length. Indeed, under the influence of external electromagnetic fields, telecommunication cables, which comprise several conductors, are subject to a stray current which disturbs the devices connected. This current, called the common mode, often drains to ground.
Measurements in the rail sector: Railways are particularly well protected against lightning and voltage surges. The poles bearing the catenary, the rails and sometimes even the fences are connected to the ground. In addition, to obtain a lower ground resistance, the poles, rails and fences are interconnected to create a network of multiple grounds set up in parallel.
Ground measurement on buried or surface pipelines: The ground connection of the pipeline is checked with a ground clamp by ground-loop and low-current or leakage-current measurements. In the case of pipelines, the presence of several independent but neighbouring ground networks may cause a significant difference in potential leading to dangerous stray currents. In order to prevent this, specific connections are set up to interconnect the various ground networks, thus guaranteeing their equipotentiality..
