中文摘要 | 根據本文互電阻理論所計算得出的地表面視在互電阻值,可確定測量大地電阻係數的四電極測試法為很精確及很可靠的。當加上燒礦、工業用鹽、焦碳等接地電阻減低劑,可使接地電阻降低約30%左右,且經過八個月觀察,減低劑崗未有流失現象,因此可用來改良運動場所、建築物的接地保護。 |
英文摘要 | The apparent mutual resistance of the Earth’s surface was found by the four-electrode measurement method and compared to calculation of the resistance by the Mutual Resistance Theorem. Sulfur residuum, industrial salt and coal was buried and, during an eight-month study period, was found to decrease the grounding resistance about 30%. It was also found that the buried materia1s were not lost during that time. |
