초록
The resistivity of soils around ground electrodes is changed considerably according to the factors such as soil types, water contents, grain size, temperature and pressure. In this study, ionization characteristics of different soil types containing the same amount of water content due to the impulse voltages are investigated. In order to analyze soil ionization phenomena, critical electric field intensity for ionization and pre-ionization and post-ionization resistances are measured and discussed.
