Interaction between interconnected and isolated grounding systems: a case study of transferred potentials

摘要

The effect caused by ground fault current in a udcomplex system of interacting electrodes is theoreticallyudstudied. The calculation applies to a specific caseudin which a set of interconnected electrodes, whichudare part of a grounding facility network, are activatedudby a ground fault current. Transferred potentials toudadjacent passive electrodes are calculated and the udmost relevant parameters of the electrode systemudare evaluated. Finally, the convenience of connectingudthe grounding electrodes is discussed.
