초록
This paper presents the characteristics and effects of grounding resistor and impedance. In grounding system, Grounding resistor is governed neutral currents and voltage. It seems that, grounding resistor has 0 value, then circuit has no faults. While if grounding resistor has large value, then neutral current has large value of fault current and it is made a damage to the utility. In order to analyze the grounding impedance characteristic, EMTP simulation has been used. The grounding impedance characteristic has been analyzed and tested for various grounding arrangements and electrode circuit shapes.
