Analysis and Calculation of Circulating Current in Grounding for Power Cables

Abstract

For the analysis of power cable line grounding circulation, we briefly introduced power cable metal sheath grounding mode and cable circulation analysis model in the first. Then, power cable support equations for calculating the circulation layer is derived. Combined with case analysis, different laying metal sheath of the induced voltage is calculated. The cable lines of the actual test results are similar to the calculation values, verifying the correctness of the analysis and calculation.
