Impulse Impedance of a Rod type Grounding Electrode

봉형접지전극의 임펄스임피던스 도출

The impulse impedence of grounding system must be accurately evaluated for a safe grounding design. However, a calculation nettled of the impulse impendence of a horizontal grounding electrode has not been established yet. This paper presents a method to compute the impulse impedance of a rod type grounding electrode and deals with the analysis of the transient characteristics on the electrodes.
