Method and Apparatus for Measuring Ground Impedance in High Frequency Region

摘要

Field of the Invention [0002] The present invention relates to a method and an apparatus for measuring a ground impedance in a high frequency region, and more particularly, to a method and an apparatus for measuring a ground impedance in consideration of characteristics in a transient state.;In the past, in Korea, only the normal ground resistance which does not take into consideration the characteristics in the transient state has been measured.;Accordingly, in the present invention, a potential [V] signal that is higher than the current flowing to the ground network by the variable frequency power generator and the ground potential (ground potential: zero potential of the infinite origin) is measured and the measured signals are used to calculate the ground impedance So that the magnitude and the phase of the ground impedance are detected, and the data of the determined ground impedance according to the selected frequency band is output according to the user's selection. Thus, in the high frequency region A method and apparatus for measuring ground impedance are provided.
