Optimal compensating schemes for the secondary arc current limiting using neutral reactor for 1000 kV ultra‐high voltage long parallel transmission lines in maintenance state are investigated in this study. For maintenance safety, the line in maintenance must be electrically isolated from the line in normal operation state. The influential factors such as transposition degree, arc resistance, load current and fault location are studied. Finally, the sensitivity of secondary arc current against the variation of neutral reactor value is investigated. Real‐time digital simulator (RTDS) simulation tests have been carried out to verify the correctness and validity of the analysis presented in this study.
