Chauvin Arnoux CA 6418 Earth ground clamp meter

Earth clamp CA 6418 with long probe for clamps
The Chauvin Arnoux CA 6418 earth clamp is specially designed for testing ground loops on tape electrodes. Their long measuring head securely encloses flat steel bands without interrupting the cable and without the use of earth spikes. The device is designed for daily use under demanding conditions.

The CA 6418 records the loop impedance of an earth system without contact using the clamp measurement principle: An excitation winding in the measuring head generates a defined AC voltage, a receiver winding measures the resulting current - from this the loop impedance is calculated. The special strength lies in the elongated measuring head: It enables the clamping of flat bands of different widths, which cannot be detected with conventional round pliers. In addition to the resistance measurement, the device detects leakage currents in the earthing network and warns with an adjustable alarm when predefined thresholds are exceeded This makes the device suitable for routine tests as well as for safety-critical inspections.

Your benefits at a glance
· Longer measuring head especially for bands – enables reliable measurement on flat bands that round pliers cannot detect
· Measurement without interruption of conductor and without earth spikes – saves time and allows testing in hard to reach environments
· On-site adjustment without manufacturer feedback – the optional calibration loop CL1 with 5 fixed resistance values enables the automatic testing and adjustment of the pliers directly via the integrated setup
· Adjustable alarms for resistance and current – warns reliably when defined limiting values are exceeded
· Automatic adjustment of the air gap when switched on – ensures stable and reproducible measurement results
· Automatic PRE-HOLD mode – measured values are frozen in the display when the ammeter is opened
· Storage for 300 measurements with time stamp directly in the device

Typical areas of application:
· Earthing tests on lightning protection systems with bands
· Earth tests in areas where ground spikes cannot be introduced into the ground
· Parallel earthing measurement in high and low-voltage transformer stations
· Earthing test in the city area and in Faraday-protected buildings
· Measurement on telecommunication cable networks (shielding earthing, common mode current)
· Earthing control on railway tracks (masts, rails, fences)
· Inspection of earthing equipment on above and underground pipelines
· Testing of meshed earthing systems and foundations

Accessories
The optional calibration loop CL1 allows you to check the correct display and to independently adjust the pliers using the built-in setup - without sending them back to the manufacturer.
