Unusual ground clamps…
The C.A 6417 earth clamps, supplied in their transport case, allow quick measurement of earth loop resistances. 600 V CAT IV, the C.A 6417 indicate the contact voltage with dangerous voltage alarm and guarantee additional security during the measurement.
The gripper is made easier to use thanks to ergonomic innovations such as a force compensation system for effortless holding of the gripper in the open position, an OLED display, which guarantees optimal visibility at an angle of 180°, in all lighting conditions.
An automatic “pre-HOLD” mode when the clamp is opened, as well as the air gap calibration when starting it up, guarantee optimal processing of the measurements provided by the clamps.
They have a simultaneous display on the same screen of:
- impedance and leakage current (Ω+A),
- supply of contact voltage,
- the decomposition of the resistive and inductive part of the ground impedance,
They also allow visualizing the transposed impedance at a frequency that is close to the network frequency, thus minimizing measurement errors.
