内容記述 | The earth resistance of a earth plate may change daily according to the weaiher. We measured daily the resistance during 35 days from July 12, 1961. The resistance is about 200 ohms on rainy days, and about 300 ohms on fine days. It increases at the rate of 50% when the ground is very dry. The earth resistance of the copper wire buried cirularly shaped in the ground at the depth 30 cm depends on its length and the empirical formula is determined. lt is nearly reciprocally proportional to ihe length of the wire. The resistance of a good earth is lower than 10 ohms. The effective method preparing a good earth is to bury the cirularly shaped copper wire of adequate length. | |||||

内容記述 | 接地抵抗測定器で測定した接地板の抵抗は,その時の大地の状態における抵抗であって一定のものではない。 雨が降ったり晴天が続いたりすれば,大地の水分合有率が変るから接地抵抗も変るはずである。 どの程度の変化があるか実験を試みた。 |
