Abstract: When lead sheathed single conductor cables are used on alternating current circuits new problems are introduced such as induced sheath voltages and sheath losses. In this thesis it is proposed to consider sheath voltages, currents and losses and line constants for one or two circuits of single conductor cables with non-magnetic metallic sheaths. Residual earth currents, abnormal sheath voltages during failures, sheath proximity losses, and the results of special sheath bonding and of sheath and conductor transpositions will also be considered. Induced sheath voltages, sheath circulating currents, and the resulting values of sheath losses and apparent conductor impedance are the most important quantities from a practical operating standpoint. It will be shown that many practical cable arrangements are special cases of one more general case with a single surprisingly simple solution for these quantities.
