탄소접지봉의 접지임피던스의 저감효과

초록

This paper deals with the frequency-dependent ground impedance of grid with carbon ground electrodes. Grid with carbon ground electrodes is generally valid for lightning protection systems. Carbon ground electrodes may be used as auxiliary ground electrodes to reduce the high frequency ground impedance. The ground impedance reduction is obtained when the test current is injected at the terminal of carbon ground electrode.
