Chauvin Arnoux CA6416 Earth Clamp
The C.A 6416 earth clamps, delivered in a carrying case, are ideal for quick earth-loop resistance measurements. 600V CAT IV, they display the earth voltage with a dangerous voltage alarm and provide additional safety during measurement.
They are particularly easy to use thanks to ergonomic innovations such as a force compensation system to keep the clamp open without any effort and an OLED display, offering visibility over an angle of 180° whatever the lighting conditions.
The automatic PRE-HOLD function when the clamp is opened and the automatic jaw calibration function at power-up help to optimize processing of the measurements provided by the clamps.
Chauvin Arnoux C.A 6416 Comes Supplied With:
- Carrying Case
- 4 x 1.5 V batteries
- CD-Rom containing the operating manual in 5 languages
Simultaneous display of:
- The impedance and leakage current (Ω+A),
- The earth voltage,
- The breakdown of the resistive and inductive parts of the ground impedance,
Also allows user to display the impedance transposed to a frequency close to the network frequency, thus reducing measurement errors when low values are involved.
- Additional specifications:
- Large measurement range: 1,500 Ω / 500 µH / 40A
- Alarms on Ω, A and V
- Automatic Pre-Hold mode when the clamp is opened
- 300 storage locations
- Real-time clock for time/date-stamping of measurements
- Automatic calibration of jaw opening distance at start-up
- Buzzer and automatic power-off
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.
GTC Ground Tester Clamp software (Additional)
The GTC (Ground Tester Clamp) software can be used to control C.A 6417 communicating earth clamps.
GTC is a tool for:
- Configuring the instruments,
- Downloading and viewing the data stored in the memory and saving them (creation of a *.icp file)
- Perform instantaneous acquisition operations,
- Exporting the measurement data into DATAVIEW (*.dvb files) or an Excel spreadsheet (*.csv or *.xls files)
*Dataview software is not supplied with this version of GTC
