Joint / random direct buried telco/power requires grounding every 8 times per 1.6 km (1 mile).

Grounding strategy for direct-buried telco/power joints aims to keep the ground potential rise low and provide a reliable fault-current path along the run. By placing a grounding point every 1.6 km divided by eight, you get about 200 meters between points. This interval helps keep the impedance between adjacent ground points low enough that a fault current can quickly return to earth, reducing dangerous surface voltages at joints and along the trench, and it also makes testing and maintenance more straightforward. If the grounding points were spaced farther apart, the impedance could rise enough to allow higher voltages to appear at equipment or along the surface during faults; closer spacing increases protection but adds cost with limited additional safety gain.
