HVDC Deep-well grounding electrode covers a small area, which effectively alleviates the problem of difficulty in selecting the site of grounding electrode. Due to the small number of electrodes, each sub-electrode has to bear tens of times the curre

As natural lightning strikes on a transmission tower, lightning current will flow along grounding lines into the adjacent tower grounding grid. As lightning current is dispersed from the tower grounding grid into the soil, a lightning overvoltage may
