Smart Navigator 2.0 HV
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 HV 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 into 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.
Power supply
The Smart Navigator 2.0 HV harvests the energy for its power supply from the overhead line current. Thanks to dynamic adaptation of its operation to load conditions, a load current of 5 Amps suffices.
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.
Clamp
Thanks to the innovative clamping mechanism, unintentional detaching from the overhead line due to environmental influences is impossible.
With a hotstick, the Smart Navigator 2.0 HV 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.
- Intelligent fault detection – reduces outage times
- Overhead line monitoring – data for the evaluation of the network condition
- Energy Harvesting – simply clipped onto a phase conductor of the overhead line
- Innovative installation - on live conductors and from the ground
- Remote maintenance – configuration and updates from the control room
