Effective Resistance and Inductance of 3-Conductor Shipboard Power Cables

The effective resistance and inductance of 3-conductor shipboard power cables are measured at frequencies up to 800 cycles per second. The effects of conductor spacing, steel armor, and adjacent magnetic materials are described. The results indicate that the effective resistance is increased greatly as the conductor separation is reduced and that both the steel armor on the cables and other adjacent magnetic materials increase the effective resistance and inductance of the cable.
