| Abstract |
This paper deals with the frequency-dependent grounding impedances of counterpoises relevant to the soil resistivity, the length of counterpoises and the feeding point of test current. The grounding impedances of counterpoises buried in one-layered and two-layered soils were measured and analyzed in the frequency range from 1[㎑] to 10[㎒]. As a result, the frequency-dependent grounding impedances strongly depend on the soil resistivity, and the grounding impedances within the frequency of several tens [㎑] are capacitive behavior in high soil resistivity. When injecting the ground current to the end of counterpoise buried in soil with high resistivity, the grounding impedances in high frequency are increased. |
