Effect of Impulse Polarity on a New Grounding Device with Spike Rods (GDSR)
The characterizations of grounding systems subjected to high impulse conditions are known to be dependent on the polarity, current to peak time and discharge time, as well as the electrical properties of the soil, and the grounding electrodes themselves.

Research on the Interaction Between Multi-Circuit Shared HVDC Grounding Electrodes
[Introduction] Unlike the independent grounding electrode, shared earth electrode is connected to multiple DC (Direct Current) systems, and its parameters and operation mode need to be determined by each system connected to it.
