Abstract
Disclosed herein are systems and methods for safe electric power delivery protection within a high-risk area while maintaining electric power availability in non-faulted areas. Fault signals from wireless sensors are used at a recloser to block reclosing onto a faulted high-risk zone. Fault signals from wireless sensors are used at a recloser to permit reclosing when the reclosing operation will not close onto a fault location within the high-risk zone. Portions of the power system may be selectively openable by sectionalizers. When a fault is reported by a wireless sensor as being on a portion of the power system selectively openable, a recloser may be permitted to attempt a reclose operation affecting the high-risk zone and the selectively openable portion.
