This study presents a novel capacitive coupling compensation scheme for 500 kV four‐circuit transposed parallel transmission lines. Using this scheme, the capacitive coupling between energised phase and faulted phases in four‐circuit can be fully compensated. Moreover, the secondary arc current can be limited to <10 A. On the basis of the new scheme, an optimal compensation scheme for every kind of maintenance state is also depicted. Performances of the proposed schemes are validated by real‐time digital simulator.
