An underground power distribution network that clears faults using detected traveling waves. The network includes a power source, a feeder receiving power from the power source, and a plurality of series connected switchgear disposed along the feeder. Each switchgear includes at least one current interrupting device for interrupting current on the feeder, at least one current sensor for measuring current on the feeder, and a controller responsive to current measurement signals from the current sensor. A communications link provides communications between the controllers. The current sensors detect traveling waves as a result of a fault on the feeder and the controllers broadcast messages on the communications link identifying whether the controller receives positive polarity or negative polarity traveling waves that identify whether the fault is downstream or upstream of the switchgear so as to determine which current interrupting device will be opened to clear the fault.
