1. A method for accelerating a fault localization process in an alternating current, polyphase powerline system utilizing a plurality of reactance injecting elements to inject reactance for load balance among phases of the polyphase powerline system, the method comprising:
sensing a fault current by one of the reactance injecting elements in any one phase of the polyphase powerline system;
creating a message indicating the sensed fault current; and
transmitting the message through a dedicated channel to one or more of the plurality of reactance injecting elements in other phases of the polyphase powerline system to reduce the injected reactance for every phase to approximately zero in a time that is short compared to a cycle of the alternating current.
