접지전류의 입사점에 따른 수평 접지전극의 접지임피던스의 수치계산

초록

This paper presents the frequency-dependent ground impedance of a horizontal grounding electrode associated with the injection point of ground current. The ground impedances of 10 m and 30 m horizontal grounding electrodes are numerically calculated when the current source is injected at the center and the end of the electrode. When the current source is injected at the center of horizontal grounding electrode, the Delta-gap source model was applied to calculate the ground impedance and phase. The ground impedance of a horizontal grounding electrode as the test current is injected at the center of the electrode over the specified frequency is lower than it as the test current is injected at the end.
