Abstract: The special grounding of cables serves to suppress the induced circulation of the metal sheath to enhance the current carrying capacity of cables. Furthermore, it is significant for high-voltage single-core cables undertaking high-ampacity transmission tasks. The paper introduces a novel cable grounding approach designed to overcome the limitations of existing methods. This approach suppresses the induced circulating current in the metal sheath by introducing grounding resistance at both ends, thereby disrupting the balance of the induction circuit. The paper presents six segmented types tailored to short and long lines for practical application. Theoretical calculations and analyses have been conducted to assess the effectiveness of each type in suppressing induced circulating current. Additionally, the substantial improvement in capacity has been verified through the IEC and finite element methods. The comprehensive engineering performance of this novel grounding approach has also been examined in terms of economic reliability, uneven segmentation, induced voltage, and fault emergency response. The findings reveal that, compared to traditional methods like single-point grounding and cross-bonding, the proposed grounding technique offers practical advantages and potential, providing an enhanced reference for grounding high-voltage single-core cables.
