The CA 6474 supplements the CA 6472 earth and resistance meter for measurements on high-voltage pylons.
The following measurements can be made with the CA 6474 in conjunction with the CA 6472:
- Total earthing resistance of the pylons
- Earthing resistance of the individual mast feet
- total impedance of the line
- Connection quality of the ground wire
- Active measurement (current via CA 6472)
- Passive measurement (use of noise voltages)
