LIGNARD – installing sensors without de-energizing the line.
A robotic solution to position sensors on live HV/EHV conductors, with a ground team and limited logistics.
Use cases
Instrument the grid without shutting it down.
Installation on HV/EHV lines
Direct installation of sensors on live conductors, with no grid outage.
Real-time monitoring
Continuous supervision: current, temperature, vibration, mechanical condition of structures.
Predictive maintenance
Actionable field data to anticipate failures and prioritize interventions.
Custom instrumentation
Installation of sensors tailored to the grid operator’s business needs.
Ground-based operator
No human work at height, no contact with the live line.
Rapid deployment
Faster implementation with a small team and no heavy logistics.
