火山灰地における接地抵抗について
On the Earthing Resistance in the Area of the Volcanic Ashes
品田, 雄治
application/pdf
It should seem to be difficult to get the good earthing in the area of the volcanic ashes. There are several ways to calculate the earthing resistance theoretically, but in practice it differs by various factors. In these factors the contact resistance between the earth and the grounding electrode is given much weight. Here it has been assumed that the earthing resistance is composed of one resistance which may be calculated by the resistivity of the ground and of another that may be the contact resistance between the earth and the earthing electrode,and in the area of the volcanic ashes the contact resistance between the simple grounding bar and the earth has been got experimentaly for the shallow part of the ground. To the ground about one meter deep,it has been concluded that the earthing resistance is composed of the contact resistance between the earth and the earthing bar in the area of the volcanic ashes
