Abstract :
The characteristics of transient voltage, current and grounding resistance of a spokewise grounding electrode is investigated based on field measurements. The grounding electrode is composed of 8 reinforcing steel bars with diameter of 10 mm, every bar with the length of 2 m, and is buried at the depth of 0. 6 m from the ground surface. A pulse discharge from a high-voltage capacitor is applied at the center of the grounding electrode to observe transient voltage and current on it. The measured results are illustrated, the transient grounding resistance is calculated and analyzed.
