Designed for overhead distribution circuits, the SMART NAVIGATOR fault indicator quickly and
accurately aids trouble crews in determining the status of the system and the location of faults.
Installed directly on the overhead conductor the unique design allows easy installation and/or removal
with a hot stick.
The SMART NAVIGATOR is specially designed and engineered for Smart Grid – Distribution
Automation (DA) applications. The SMART NAVIGATOR indicates a fault locally by LED and also over
a wireless radio link. The wireless link is established with a SMART NAVIGATOR compatible
concentrator that makes this information available for remote monitoring via a RTU. The fast SCADA
room availability of FCI status information helps drastically saving time for the identification of the
faulty line section. This substantially speeds up the process of restoring the power supply to the utility
customers.
In addition the SMART NAVIGATOR continuously monitors and transmits circuit status information
which helps to identify distribution grid capacity, improves grid planning and supports analysis of
predictive or post-fault switching decisions.
A SMART NAVIGATOR compatible concentrator as located within a SMART RECEIVER connects
with up to 12 SMART NAVIGATOR FCIs. Communication between the concentrator and the SMART
NAVIGATOR uses wireless radio frequency technology in the world-wide license-free 2.4GHz band.
Application Example: The figure below shows a typical application for the SMART Navigator.
Figure 1.1: Application example for SMART RECEIVER
Status information about the overhead line is sent from the SMART NAVIGATORs to the SMART
RECEIVER which resides inside a pole mounted RTU. The SMART RECEIVER relays the information
to the RTU which itself transmits it over a network, e.g. cellular GSM network, to a SCADA head-end
for the network control room integration.
