Abstract :
Counterpoises are recommended for protecting electric power transmission lines against damage from lightning surges where other methods do not reduce the tower footing surge impedance to the desired level. In this paper a physical explanation of the theory of counterpoises is given together with an analytical solution of parallel counterpoise problems. Of the 2 types studied, the parallel counterpoise is shown to be the more effective.
