Why Network Operators Need an Overhead Line Monitoring System
Ageing infrastructure leads to frequent faults, while adverse weather causes downed lines and outages. Regulatory demands for reliability and safety adds pressure, requiring minimised downtime and risks to public and field teams. Couple this with extensive networks in rural areas, and overhead line fault location becomes time-consuming and costly.
Predict, prevent, protect with LineSIGHT
Linesight is a proven overhead line monitoring system specifically designed detecting faults on HV overhead distribution networks at precise locations—enhancing network resilience, safety and efficiency.
It integrates advanced sensors to continuously monitor key parameters including current, voltage, and network geometry. This enables early detection of anomalies, precise fault location within 300-500 metres, and the identification of complex issues like lowered lines, low hanging conductors and nested faults even without power.
Making Overhead Networks Safe, Reliable, and Efficient
What LineSIGHT Delivers
Fault location
Identifies faults within 300-500 metres, accelerating repairs and supporting automated restoration schemes.
Instant alerts
Delivers instant notifications of anomalies or faults, enabling quick response and minimising downtime without physical inspections.
Predictive analytics
Uses historical data and machine learning algorithms to detect developing issues like component degradation early.
Real-time visibility
Provides real-time visibility of downed lines which reduces the significant safety risks to the public and field teams.
Nest faults spotlight
“Nested faults occur when secondary damage happens after an initial outage, often during storms when power is cut, making traditional detection impossible as no current flows. Linesight excels here – using advanced sensors to monitor network geometry and disturbances (even without power), it accurately locate these hidden issues within 300 metres.”
