Assessing induced sheath voltage in multi-circuit cables: revising the methodology
Flow of current in a cable conductor generates a magnetic field which could induce current flow in the metallic cable shield or sheath.

| Summary: | Flow of current in a cable conductor generates a magnetic field which could induce current flow in the metallic cable shield or sheath. This paper examines induced voltage calculation in multi-circuit of the cables with the hope of proposing new methodology for induced sheath voltage computation in metallic shield of a single-core power cable operating in a triple circuit. This study considers a few examples to demonstrate the method of examining the induced voltage in single, double and triple-circuits. The calculated values for induced voltages were 0.079 V/m, 0.074 V/m and 0.068 V/m for triple, double and single circuit. It is found that induced sheath voltage increased with the increase in number of the cables. |
