A Study on coupling Coefficients between adjacent Earth Systems
Authors: , ,
Abstract: This paper proposes a calculation method and a measurement method of coupling coefficients between adjacent earth systems. We consider the different earth systems which are installed nearby. An abnormal current such as a power fault current flowing into one earth system may raise the potential of another earth system and damage the equipment connected to it. For this reason, it is necessary to make the earth potential rise between earth systems more clear. Therefore, we have derived a method for calculating the coupling coefficients between adjacent earth systems composed of complicated electrode arrangement. We applied the current superposition method for the calculation. We also propose two simple and accurate measurement methods of them. As a result of measuring the actual earth systems in the fields, it was confirmed that the calculated values and the measured values are in good agreement.
