    • A system for measuring a variation of ground resistance is provided to utilize the variation as a coefficient value of a season change at similar regions by measuring the variation of the ground resistance after constructing a ground. A system for measuring a variation of ground resistance includes a measuring unit and a control unit(220). The measuring unit measures resistance between a ground electrode and a ground. The control unit converts the resistance value measured from the measuring unit into digital data. The control unit calculates the variation according to the variation factor of at least one resistor. The control unit outputs the variation of the resistor to outside thereof according to the variation factor of the inputted resistance by receiving the variation factors of the resistor from the outside.
    • 提供一种用于测量接地电阻变化的系统,以通过测量构造地面之后的接地电阻的变化来将变化作为相似区域的季节变化的系数值。 用于测量接地电阻变化的系统包括测量单元和控制单元(220)。 测量单元测量接地电极和地面之间的电阻。 控制单元将从测量单元测量的电阻值转换为数字数据。 控制单元根据至少一个电阻器的变化系数来计算变化。 控制单元通过从外部接收电阻器的变化系数,根据输入电阻的变化系数将电阻器的变化输出到外部。
