Abstract Traditional single-terminal impedance-based fault location methods always have a low accuracy due to the influence of the fault transition resistance and remote terminal system impedance. Since single-phase-trip for single-line-to-ground fault is widely applied in the transmission line, while the opposite terminal system information can be available in this open-phase operation status, it is possible to accurately pinpoint the fault using this extra information. However, existing post-single-
