Fault Indication System

The RadioRANGER™ Wireless Fault Indication System reduces the time to find power failures by leading line crews to the location of underground faults. Wireless Interface ID, phase, and way distinctions display fault path information in each vault while differentiating between fault indicators in adjacent vaults. A red LED and audible annunciation indicate the presence of a faulted phase.
