Intelligent fault detection
The proven overcurrent detection alogrithm detects fault currents reliably under a wide range of network situations. Individual parameter settings tailor the Smart Navigator 2.0 LC perfectly for all locations in your overhead line network, eliminating false tripping.
Whenever a fault is detected, besides the fault information, also all monitoring data is signalled to the control room – this gives full visibility on the network condition before and after the fault occurred.
Fault messages containing information about fault direction, voltage interruption, current drop and increase in conductor temperature support the problem detection and root cause identification. Every fault is signalled to the control room within 1 minute.
For overhead lines with base loads smaller than 5 A, pole-mounted units with solar panels are used to ensure supply and control room communication. Alternatively, these can be powered from a DC or AC auxiliary power supply.
The high battery capacity of the Smart Navigators guarantees a service life of >10 years, and any load current extends the service life. Thanks to the solar or auxiliary power supply, the pole-mounted units can communicate with up to nine Smart Navigator devices simultaneously, thus monitoring and remotely reporting three overhead line sections.
Remote signalling and monitoring
Thanks to remote signalling, the complex, high-quality and diverse sensor technology enables clear monitoring and thus direct insight into your overhead line network. Sections containing decentralized feed-in points are clearly identified by the remotely reported load flow direction.
Remote maintenance such as software updates or configuration adjustments can be performed via the GSM / LTE connection.
The overhead line conductor temperature is measured and remotely reported, enabling optimal load control by the control room.
Thanks to the innovative clamping mechanism of the Smart Navigator 2.0 LC, unintentional detaching from the overhead line due to environmental influences is impossible.
With a hot stick, the Smart Navigator 2.0 LC can be mounted on an overhead line up to 12 meters high, even under live conditions. Likewise, it also can be uninstalled again without any problems.
The pole-mounted units can be attached in various ways to all sorts of overhead line poles.
The pole-mounted units feature an internal GPS sensor that provides excact position of the installation to the control room.
