The C.A 6474 is designed for use with the C.A 6472 earth tester to measure pylon earths
When used with the C.A 6472, the C.A 6474 allows the following types of measurements:
- Global earth of pylons
- Earth resistance of each of the pylon's footings
- Quality of the overhead protective earth cable connection
- Active measurement (injection by the C.A 6472)
- Passive measurement (use of stray currents)
