Overhead line sag and dynamic rating
Automated monitoring of line sag and temperature
- Our sensors measure strain, vibration and temperature directly on live conductors
- All measurements are time synchronised
- Optionally measure current or voltage at the ends of the line
- Sensor lifespan 25 years+
- Sensors require no periodic recalibration
- No ongoing maintenance – no batteries or electronics
- Sensor operational temperature range -40°C to +250°C
- We work in partnership with leading fiber installers to deploy the solution

Synaptec’s line sag solution deliverables
- Detecting ice loading on a cable or overhead line at up to 100 km from substation
- Provides time-synchronized temperature, vibration and strain measurements
- Works where there is no access or power (e.g. remote locations, extreme cold, or deserts)
- Live Synthesis dashboard – Early warning of ice build-up and sag

Why the Synaptec solution is different
- All sensors are passive – no power supply or telecoms equipment
- All measurements are time synchronized
- We measure current, voltage, temperature, vibration, and strain
- Sensor lifespan 25 years+
- All voltage levels compatible up to 500 kV
- Sensors require no periodic calibration
- No ongoing maintenance e.g. batteries or electronics
- Sensor operational temperature range -40°C to +250°C
- Uses standard single mode fibre
- Safer fitting and operation due to optical isolation of all sensors
