safety ground

基本解释

Adding vertical rods to grounding system will decrease the seasonal coefficient and stabilize the safety of grounding system.
採用垂直接地極能減小接地系統的季節系數，起穩定接地系統安全性能的作用。
Seasonal coefficients affect the safety of grounding systems and increase with the thickness and resistivity of the soil layer.
季節因素將影響接地系統的安全性能。季節系數隨冰凍季節形成的地表高阻層的電阻率及其厚度的增加而增加。
The seasonal factor affects the safety of grounding system, and causes changes in the grounding resistance, the step and touch voltages on the ground surface above the grounding system.
季節因素將影響地網的安全性能，導致地網的接地電阻、接觸電壓和跨步電壓的改變。
