봉상 접지전극 주변에서의 토중방전현상

초록

Electrical conduction in soils depends on the grain size, compactness, humidity and etc. When a high current is injected into the soil, and the breakdown phenomenon occurs and electrical behaviors in the vicinity of grounding electrodes may be changed. In the present work, electrical behaviors in the vicinity of ground rod due to the injection of impulse current were investigated. Spark-over phenomena at the tip of ground rod depends of the grain size and kinds of soil.
