Abstract
This paper presents a non-conventionally installed HV/MV underground substation from the point of view grid resistance. The effects of the infeed high voltage (HV) cables and the connected medium voltage (MV) distribution cables on the resultant earthing resistance are studied. The grid resistance was calculated by the CDEGS software code in the design phase. Further more the grid resistance was measured both before and after the installation and jointing the connecting cable lines. The paper presents results on the frequency dependence of the grid resistance as well.- Title
