Abstract
Simulated ground-fault tests (50-700 A) of various cable, ground wire, and conduit configurations are made to determine the proportion of the total ground-fault current carried by the cable metallic shield. The percentage of the total fault current for the various return paths is tabulated, along with representative zero-sequence circuit impedances. General guidelines for protecting cable shields from damage are presented.
