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.
