Based on the prevention of base station transformer from lightning, it analyzes the rise of earth potential on base station earth mat when the iron tower is struck by lightning, and the influence on base station transformer. It points out that the rise of earth potential is the reason of transformer damage. It gives the methods on preventing the damage of transformer from lightning. Final y it also gives the specific requirements on instal ation position of SPD in base station.
